The `Where.*` DSL already has `contains`, `notContains`, `idIn`, `idNotIn`, `documentContains`, and `documentNotContains`. The only open question is whether Phase 3 Search API types (`SearchResult`, `Knn`, `Rrf`, `GroupBy`, `ReadLevel`) will be available when Phase 5 runs — this phase depends on Phase 3 completing first. + +**Primary recommendation:** Name the test class `SearchApiCloudIntegrationTest` (suffix `IntegrationTest`) so the `integration` Maven profile and the `v2-integration-test` CI job run it with cloud credentials. Use `@BeforeClass` for shared seed collection setup and `@Before`/`@After` for per-test isolated collections. + +--- + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| JUnit 4 (`junit:junit`) | 4.13.2 | Test runner, `@Test`, `@Before`, `@After`, `@BeforeClass`, `Assume` | Already used throughout the codebase | +| `Assume.assumeTrue` | (part of JUnit 4) | Credential gating — skip without fail | Project-wide pattern, consistent with D-02 | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| `tech.amikos.chromadb.Utils` | project-local | `.env` loading, `getEnvOrProperty()` | All credential loading | +| `ChromaClient.cloud()` builder | v2 | Cloud client construction | Auth, tenant, database, timeout | +| Phase 2 `IndexingStatus` / `collection.indexingStatus()` | v2 | Polling wait for indexing completion (D-09) | After `add()` before search assertions | +| Phase 3 Search API (pending) | v2 | `SearchResult`, `Knn`, `Rrf`, `GroupBy`, `ReadLevel` | All CLOUD-01 search tests | + +### Installation +No new dependencies required.

Shared seed collection uses `@AfterClass`. + +### Pattern 5: Distance-Space Config Round-Trip +**What:** Create collection with explicit `space()` in `CollectionConfiguration`, verify `col.getConfiguration().getSpace()`. +**When to use:** CLOUD-02 distance space variant tests (D-18). + +```java +// Using existing CollectionConfiguration builder +CreateCollectionOptions opts = CreateCollectionOptions.builder() + .configuration(CollectionConfiguration.builder().space(DistanceFunction.COSINE).build()) + .build(); +Collection col = client.createCollection(name, opts); +// After creation: +assertNotNull(col.getConfiguration()); +assertEquals(DistanceFunction.COSINE, col.getConfiguration().getSpace()); +``` + +### Pattern 6: Mixed-Type Array Client Validation (D-22) +**What:** Metadata map containing a Java `List` with elements of mixed types must be rejected before HTTP call. +**When to use:** CLOUD-03 mixed-array test. +**Gap to investigate:** The current codebase does not appear to have explicit mixed-type array validation at the metadata serialization level. If `ChromaDtos` or `ChromaHttpCollection` silently accepts `List` with mixed types, Phase 5 must add client-level validation. This needs confirmation during implementation. + +### Anti-Patterns to Avoid +- **Fixed sleep instead of polling:** chroma-go uses `time.Sleep(2s)` — Java uses `indexingStatus()` polling per D-09. +- **Splitting tests per requirement:** D-01 mandates single class. +- **`@BeforeClass` without `@AfterClass`:** Always pair — cloud collections persist and accumulate cost. +- **Asserting exact result ordering without sorting:** Cloud result order for equal scores is not guaranteed. Assert set membership or sorted order explicitly. +- **Hard-coding collection names without UUID suffix:** Cross-test interference. Always suffix with UUID. +- **Not tracking per-test collections:** All collections created in a test must be tracked for cleanup even if assertions fail mid-test. + +--- + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Credential loading | Custom env reader | `Utils.loadEnvFile(".env")` + `Utils.getEnvOrProperty()` | Already handles env/system-property fallback | +| Test skipping on missing credentials | System.exit or throw | `Assume.assumeTrue()` | JUnit 4 skips gracefully, not fails | +| Indexing wait | Thread.sleep loops | `indexingStatus()` polling pattern | Deterministic, testable, already in existing cloud tests | +| Cloud client construction | Raw HTTP client | `ChromaClient.cloud().apiKey().tenant().database().timeout().build()` | Auth, tenant scoping, timeout wired in | +| Filter DSL | Manual map construction | `Where.idIn()`, `Where.documentContains()`, `Where.contains()`, etc. | Type-safe, validated, already tested | + +**Key insight:** Every infrastructure piece is already present. Phase 5 is purely test composition using existing building blocks. + +--- + +## Common Pitfalls + +### Pitfall 1: Test Class Naming — Integration Profile Mismatch +**What goes wrong:** If new class is named `SearchApiCloudTest.java` (not `IntegrationTest.java`), the Maven `integration` profile does NOT include it. The `v2-integration-test` CI job runs `mvn --batch-mode test -Pintegration` which only picks up `**/*IntegrationTest.java`. +**Why it happens:** `CollectionApiExtensionsCloudTest` (existing) uses `CloudTest` suffix and is effectively excluded from CI cloud execution — it only runs locally with `.env`. New Phase 5 class must follow `CloudParityIntegrationTest` naming pattern. +**How to avoid:** Name the class `SearchApiCloudIntegrationTest`. Verify CI job picks it up. +**Warning signs:** CI job shows 0 tests run (no failure, just skips) when credentials are absent in unit-tests job. + +### Pitfall 2: `@BeforeClass` + `Assume` Interaction +**What goes wrong:** If `@BeforeClass` throws (e.g., null credential not caught), all tests in the class fail rather than skip. +**Why it happens:** JUnit 4 treats uncaught exceptions in `@BeforeClass` as class-level errors (fail), not skips. +**How to avoid:** Gate credentials with `Assume.assumeTrue()` in `@BeforeClass`. The `assumeTrue` in a `@BeforeClass` context causes all tests in the class to be skipped, which is the desired behavior (D-02). +**Warning signs:** Tests show `ERROR` (not `SKIPPED`) in Maven output when credentials are absent. + +### Pitfall 3: Shared Seed Collection Pollution +**What goes wrong:** A test that's supposed to be read-only accidentally mutates the shared seed collection (e.g., by calling `upsert()` or `delete()`). +**Why it happens:** D-04 mandates shared seed for read-only tests — if a test that should use an isolated collection (D-05) uses the shared one instead, subsequent tests see corrupted state. +**How to avoid:** Clearly document in code which tests use shared seed vs isolated collection. All mutating tests (upsert, delete, schema changes) must create their own collection via the `@Before` instance-level client. +**Warning signs:** Flaky tests where result counts change across runs. + +### Pitfall 4: Float/Integer Type Round-Trip (D-23) +**What goes wrong:** A float metadata value (e.g., `3.14`) is stored and retrieved as an integer or double, failing type-equality assertion. +**Why it happens:** JSON parsing layer may deserialize `3.0` as `Integer(3)` rather than `Float(3.0f)` or `Double(3.0)`. The metadata map is typed as `Map`, so runtime type is the deserialized type. +**How to avoid:** Assert using `instanceof Float` / `instanceof Double` checks plus value comparison, not `assertEquals(Float.class, val.getClass())` which is too brittle. Alternatively check `.toString()` and compare string representations. +**Warning signs:** Test assertion "expected `3.14` (Float) but was `3.14` (Double)". + +### Pitfall 5: Search API Not Yet Implemented (Phase Dependency) +**What goes wrong:** Phase 5 depends on Phase 3 Search API (`SearchResult`, `Knn`, `Rrf`, `GroupBy`, `ReadLevel`). If Phase 3 is not complete, Phase 5 tests cannot compile. +**Why it happens:** Phase ordering — current state shows Phase 3 pending. +**How to avoid:** Phase 5 must be planned but implementation blocked until Phase 3 ships. CLOUD-01 tests (KNN, RRF, GroupBy, batch, read level) are entirely gated on Phase 3 types. CLOUD-02 (schema/index) and CLOUD-03 (array metadata) can be implemented independently of Phase 3. +**Warning signs:** Compilation failure on import of `Search`, `Knn`, `Rrf`, `GroupBy`, `ReadLevel` classes. + +### Pitfall 6: INDEX_ONLY May Return Fewer Records Than Inserted +**What goes wrong:** Test asserts `count == 15` for `INDEX_ONLY` read level but gets 12 because compaction hasn't run yet. +**Why it happens:** `INDEX_ONLY` intentionally skips the WAL — recently inserted records may not be in the compacted index yet. +**How to avoid:** Per D-12, `INDEX_ONLY` tests use `<=` assertion (assert result count is at most total record count, not exactly). `INDEX_AND_WAL` tests assert exactly, and skip polling (WAL guarantees all records are visible). +**Warning signs:** Intermittent assertion failures on exact count after `INDEX_ONLY` search. + +### Pitfall 7: Mixed-Type Array Validation Gap +**What goes wrong:** A `List` containing `["foo", 42, true]` is sent to the server without client-side rejection, resulting in undefined server behavior (may succeed, may return 400, may silently drop elements). +**Why it happens:** D-22 requires client-level rejection. Current metadata serialization (`ChromaDtos`) may not validate array element types. +**How to avoid:** During implementation, grep for metadata serialization code and add type validation for `List` values in metadata maps. The test for D-22 should assert a `ChromaBadRequestException` (or `IllegalArgumentException`) is thrown before any HTTP call. +**Warning signs:** Mixed-array test passes but actually sent a request — check with network mock if unclear. + +--- + +## Code Examples + +Verified patterns from existing source: + +### Credential Gate (JUnit 4) +```java +// Source: CloudParityIntegrationTest.java (existing) +@Before +public void setUp() { + Utils.loadEnvFile(".env"); + String apiKey = Utils.getEnvOrProperty("CHROMA_API_KEY"); + Assume.assumeTrue("CHROMA_API_KEY is required", isNonBlank(apiKey)); + client = ChromaClient.cloud().apiKey(apiKey).tenant(tenant).database(database) + .timeout(Duration.ofSeconds(45)).build(); +} + +private static boolean isNonBlank(String value) { + return value != null && !value.trim().isEmpty(); +} +``` + +### Unique Collection Name +```java +// Source: CloudParityIntegrationTest.java (existing) +private static String uniqueCollectionName(String prefix) { + return prefix + UUID.randomUUID().toString().replace("-", ""); +} +``` + +### Best-Effort Cleanup +```java +// Source: CloudParityIntegrationTest.java (existing) +@After +public void tearDown() { + if (client != null) { + for (int i = createdCollections.size() - 1; i >= 0; i--) { + try { client.deleteCollection(createdCollections.get(i)); } + catch (ChromaException ignored) {} + } + client.close(); + } + createdCollections.clear(); +} +``` + +### DistanceFunction Round-Trip +```java +// Source: DistanceFunction.java (existing enum values) +// CreateCollectionOptions.builder().configuration(CollectionConfiguration.builder() +// .space(DistanceFunction.COSINE).build()).build() +// Verify: assertEquals(DistanceFunction.COSINE, col.getConfiguration().getSpace()) +``` + +### IndexingStatus Check +```java +// Source: CollectionApiExtensionsCloudTest.java (existing) +IndexingStatus status = col.indexingStatus(); +assertTrue(status.getOpIndexingProgress() >= 0.0 && status.getOpIndexingProgress() <= 1.0); +assertEquals(status.getTotalOps(), status.getNumIndexedOps() + status.getNumUnindexedOps()); +``` + +### Contains/NotContains Filter (Array Metadata) +```java +// Source: Where.java (existing) +// Where.contains("tags", "electronics") -> {"tags": {"$contains": "electronics"}} +// Where.notContains("tags", "furniture") -> {"tags": {"$not_contains": "furniture"}} +// Where.contains("prices", 29.99f) -> {"prices": {"$contains": 29.99}} +// Where.contains("flags", true) -> {"flags": {"$contains": true}} +``` + +--- + +## CI and Test Execution Architecture + +### Maven Profile Mechanics +| Command | Profile | Which Tests Run | +|---------|---------|----------------| +| `mvn test` | default (no profile) | All `*Test.java` EXCEPT `*IntegrationTest.java` | +| `mvn test -Pintegration` | integration | ONLY `*IntegrationTest.java` | +| `mvn test -Pquality` | quality | All `*Test.java` in v2 package | + +### GitHub Actions Jobs +| Job | Command | Credentials | What Runs | +|-----|---------|------------|-----------| +| `unit-tests` | `mvn test` | None (OPENAI/COHERE/HF only) | Unit tests; cloud `*CloudTest.java` files run but `Assume` skips them | +| `integration-tests` | `mvn test -Pintegration` | None | TestContainers integration tests | +| `v2-integration-test` | `mvn test -Pintegration` | CHROMA_API_KEY/TENANT/DATABASE | `*IntegrationTest.java` — including cloud parity tests | + +**Critical:** The new Phase 5 class MUST be named `SearchApiCloudIntegrationTest.java` (suffix `IntegrationTest`) to be included in the `v2-integration-test` CI job per D-03. + +### Test Execution Commands +```bash +# Run Phase 5 cloud tests locally (requires .env with credentials) +mvn test -Pintegration -Dtest=SearchApiCloudIntegrationTest + +# Run all cloud integration tests +mvn test -Pintegration + +# Verify test skips cleanly (no credentials) +mvn test -Pintegration -Dtest=SearchApiCloudIntegrationTest +# Expected: test methods report as "skipped" not "failed" +``` + +--- + +## Validation Architecture + +### Test Framework +| Property | Value | +|----------|-------| +| Framework | JUnit 4 (4.13.2) | +| Config file | Maven Surefire — pom.xml `` profile | +| Quick run command | `mvn test -Pintegration -Dtest=SearchApiCloudIntegrationTest` | +| Full suite command | `mvn test -Pintegration` | + +### Phase Requirements → Test Map +| Req ID | Behavior | Test Type | Automated Command | File Exists?

CLOUD-02 and CLOUD-03 tests do NOT depend on Phase 3 and can be planned/implemented independently. + +2. **Mixed-type array validation location** + - What we know: D-22 requires client-level rejection. `Where.java` validates inputs but metadata map values are not validated for type homogeneity. + - What's unclear: Whether `ChromaDtos` or `ChromaHttpCollection`'s metadata serialization already rejects `List` with mixed types. + - Recommendation: Implementation wave should grep `ChromaDtos` for metadata serialization and add validation if missing.

planning + + +## Phase Boundary + +Implement the Chroma Search endpoint (v1.5+) with full ranking expression DSL, field projection, groupBy, and read levels — matching Go client capabilities. Requirements: SEARCH-01, SEARCH-02, SEARCH-03, SEARCH-04. + +This phase delivers the `collection.search()` API surface, builder types (Search, Knn, Rrf, GroupBy), result types (SearchResult, SearchResultRow), the Select projection mechanism, SparseVector value type, and integration tests against Chroma >= 1.5. + + + + +## Implementation Decisions + +### Search Builder API Shape +- **D-01:** Hybrid approach — convenience shortcuts on SearchBuilder for simple KNN (`queryText()`, `queryEmbedding()` directly on the builder), explicit `Search` objects via `searches(Search...)` for batch and complex cases. +- **D-02:** Simple KNN case must be as frictionless as possible: `collection.search().queryText("headphones").limit(3).execute()` — consistent with `query()` builder shape. +- **D-03:** Batch search is first-class: `collection.search().searches(search1, search2).limit(5).execute()` — multiple `Search` objects in a single request. +- **D-04:** Both per-search filters (`Search.builder().knn(...).where(Where.eq(...))`) and global filters (`searchBuilder.where(Where.eq(...))`) supported. They combine (AND) when both present — this is how the Chroma API works. +- **D-05:** Naming follows Chroma search API terminology: `limit()` and `offset()` (not `nResults()`). This diverges from `query()` naming but matches the upstream API accurately. + +### Result Type Design +- **D-06:** Single `SearchResult` interface — no compile-time split between grouped and ungrouped results. +- **D-07:** Flat access via `rows(searchIndex)` returns `ResultGroup` — same pattern as `QueryResult.rows(queryIndex)`. +- **D-08:** Grouped access via `groups(searchIndex)` returns `List` where each group has `getKey()` (the group metadata value) and `rows()` returning `ResultGroup`. +- **D-09:** `isGrouped()` method makes the response self-describing — no magic, no auto-flattening, no runtime surprises. +- **D-10:** Column-oriented accessors preserved for QueryResult consistency: `getIds()`, `getDocuments()`, `getMetadatas()`, `getEmbeddings()`, `getScores()` (not `getDistances()`). +- **D-11:** `SearchResultRow` extends `ResultRow`, adds `getScore()` returning `Float` (null if not included). Scores are relevance scores from the search endpoint (not distances). +- **D-12:** Dual access (column-oriented + row-oriented) matches existing QueryResult/GetResult pattern for familiarity. + +### Field Projection (Select) +- **D-13:** Search uses `Select` class exclusively — no `Include` enum on search builders. Clean separation matching Chroma core and chroma-go. +- **D-14:** Standard field constants: `Select.DOCUMENT` (`#document`), `Select.SCORE` (`#score`), `Select.EMBEDDING` (`#embedding`), `Select.METADATA` (`#metadata`), `Select.ID` (`#id`). +- **D-15:** Custom metadata key projection via `Select.key("fieldName")` — returns just that metadata field, not the whole blob. Equivalent to Go's `K("fieldName")`. +- **D-16:** `select()` is per-search (on the `Search` builder), not global on SearchBuilder. Each search in a batch can project different fields. +- **D-17:** `selectAll()` convenience method sets all 5 standard fields. +- **D-18:** Wire format: `{"select": {"keys": ["#document", "#score", "title"]}}` — matches Chroma API spec exactly. + +### Sparse Vector Support +- **D-19:** `SparseVector` value type (indices + values) created in Phase 3 as an immutable value object. +- **D-20:** `Knn.querySparseVector(SparseVector)` available in Phase 3 — search API ships with full KNN input type support. +- **D-21:** Actual `SparseEmbeddingFunction` implementations (BM25, Splade, etc.) deferred to Phase 4 or later.

Grouped results also return in this same flat wire shape; grouping metadata is TBD based on actual server response (see Open Questions). + +## Common Pitfalls + +### Pitfall 1: Confusing `filter` vs `where` JSON key +**What goes wrong:** The search endpoint uses `"filter"` as the JSON key; the query endpoint uses `"where"`. Using `where` in search requests will be silently ignored or cause a bad request. +**Why it happens:** The `Where` class is reused for search filters, but the JSON key changes. +**How to avoid:** In `SearchItem` DTO, use field name `filter` (not `where`). Apply `Where.toMap()` to get the map, put it under `"filter"` key. +**Warning signs:** Server returns empty results where non-empty expected, or 400 bad request on filter operations. + +### Pitfall 2: Using `float` instead of `double` for scores +**What goes wrong:** Scores in the response are `float64` in Go / `double` in JSON. If deserialized as `float`, precision is lost. +**Why it happens:** `QueryResult` uses `List` for distances; copy-paste risk. +**How to avoid:** Use `List` for scores in `SearchResponse` DTO and `List>` for all search score fields. The `SearchResultRow.getScore()` returns `Float` per D-11 (user API), but internally handle as `Double` and downcast. +**Warning signs:** Scores appear as very slightly different values than expected. + +### Pitfall 3: Forgetting `return_rank: true` on KNN inside RRF +**What goes wrong:** RRF scoring requires each constituent KNN to return rank positions, not distances. Without `"return_rank": true`, RRF results are incorrect or empty. +**Why it happens:** `return_rank` is only needed when a KNN is used as an RRF input. It is silently ignored for direct KNN search. +**How to avoid:** When building RRF DTOs, always set `return_rank: true` on inner KNN objects. The `Rrf.builder()` should auto-set this on wrapped Knn instances. +**Warning signs:** RRF returns 0 results or all scores are equal. + +### Pitfall 4: IDIn/IDNotIn conflicts with global Where filter +**What goes wrong:** Per D-04, per-search filters and global filters combine with AND. If both include IDIn clauses pointing to disjoint sets, the result is empty. +**Why it happens:** The wire format merges filter maps; if both have `"#id"` key, one will overwrite the other during serialization. +**How to avoid:** When merging per-search and global filters in the DTO, detect `"#id"` key conflicts and either raise an IllegalArgumentException or prefer the per-search filter. Document this behavior in Javadoc. +**Warning signs:** Empty results when combining IDIn filters. + +### Pitfall 5: PublicInterfaceCompatibilityTest will fail +**What goes wrong:** `PublicInterfaceCompatibilityTest` counts methods on `Collection` interface and will fail when `search()` is added. +**Why it happens:** `EXPECTED_COLLECTION_METHOD_COUNT = 21` — adding `search()` makes it 22. +**How to avoid:** Update `EXPECTED_COLLECTION_METHOD_COUNT` in `PublicInterfaceCompatibilityTest` when adding `SearchBuilder search()`. +**Warning signs:** `testCollectionInterfaceMethodCount` test fails. + +### Pitfall 6: Search is Cloud-only in practice (Chroma >= 1.5) +**What goes wrong:** Running search integration tests against self-hosted Chroma < 1.5 will return 404 or 405. +**Why it happens:** The Search endpoint was added in Chroma 1.5. Self-hosted tests use TestContainers. +**How to avoid:** Add `assumeMinVersion("1.5.0")` in all search integration tests. The default container version in `AbstractChromaIntegrationTest` is `1.5.5` so this should pass, but add the guard for matrix test safety. +**Warning signs:** 404 Not Found on POST to `/search` path. + +## Code Examples + +### Simple KNN search (D-02) +```java +// Source: Pattern derived from QueryBuilderImpl in ChromaHttpCollection.java +SearchResult result = collection.search() + .queryText("wireless headphones") + .limit(5) + .execute(); + +for (SearchResultRow row : result.rows(0)) { + System.out.println(row.getId() + " score=" + row.getScore()); +} +``` + +### Batch search (D-03) +```java +// Source: Pattern derived from Go client SearchQuery{Searches: [...]]} +Search s1 = Search.builder().knn(Knn.queryText("headphones")).limit(3).build(); +Search s2 = Search.builder().knn(Knn.queryText("organic tea")).limit(3).build(); +SearchResult result = collection.search().searches(s1, s2).execute(); + +ResultGroup results0 = result.rows(0); // headphones +ResultGroup results1 = result.rows(1); // organic tea +``` + +### RRF hybrid search (SEARCH-02) +```java +// Source: Go RrfRank MarshalJSON → {"rrf":{"ranks":[...],"k":60}} +Knn knn1 = Knn.queryText("wireless audio").returnRank(true); +Knn knn2 = Knn.queryText("noise cancelling headphones").returnRank(true); +Rrf rrf = Rrf.builder().ranks(knn1, 0.7f).ranks(knn2, 0.3f).k(60).build(); +SearchResult result = collection.search() + .searches(Search.builder().rrf(rrf).limit(5).build()) + .execute(); +``` + +### Field projection with Select (SEARCH-03, D-13 to D-18) +```java +// Source: Select wire format {"select":{"keys":["#id","#score","category"]}} +Search s = Search.builder() + .knn(Knn.queryText("headphones")) + .select(Select.ID, Select.SCORE, Select.key("category")) + .limit(5) + .build(); +SearchResult result = collection.search().searches(s).execute(); +// result.rows(0).get(0).getScore() is populated +// result.rows(0).get(0).getDocument() is null (not selected) +``` + +### GroupBy search (SEARCH-04, D-08) +```java +// Source: Go GroupBy pattern; wire format {"group_by":{"key":"category","min_k":1,"max_k":3}} +Search s = Search.builder() + .knn(Knn.queryText("product")) + .groupBy(GroupBy.builder().key("category").minK(1).maxK(3).build()) + .limit(15) + .build(); +SearchResult result = collection.search().searches(s).execute(); +assertTrue(result.isGrouped()); +for (SearchResultGroup group : result.groups(0)) { + System.out.println("Group: " + group.getKey() + " count=" + group.rows().size()); +} +``` + +### ReadLevel (SEARCH-04) +```java +// Source: Go ReadLevel → "index_and_wal" / "index_only" +SearchResult result = collection.search() + .queryText("headphones") + .readLevel(ReadLevel.INDEX_AND_WAL) + .limit(5) + .execute(); +``` + +### Sparse vector KNN (SEARCH-01, D-20) +```java +// Source: Go KnnRank query with SparseVector → {"indices":[1,5],"values":[0.3,0.7]} +SparseVector sv = SparseVector.of(new int[]{1, 5, 10}, new float[]{0.3f, 0.7f, 0.2f}); +Search s = Search.builder() + .knn(Knn.querySparseVector(sv).key("sparse_field")) + .limit(5) + .build(); +``` + +### ChromaDtos.SearchRequest structure (for implementer) +```java +// Source: Claude's discretion per CONTEXT.md — follows established ChromaDtos patterns +static final class SearchRequest { + final List searches; + @SerializedName("read_level") + final String readLevel; +} + +static final class SearchItemDto { + final Map filter; // from Where.toMap() + final Object rank; // KnnDto or RrfDto (must serialize polymorphically) + final SearchSelectDto select; + @SerializedName("limit") + final SearchPageDto page; + @SerializedName("group_by") + final GroupByDto groupBy; +} + +static final class KnnDto { + final Object query; // String, List, or SparseVectorDto + final String key; // "#embedding" or custom sparse field name + final Integer limit; + @SerializedName("default") + final Double defaultScore; + @SerializedName("return_rank") + final Boolean returnRank; +} + +static final class SparseVectorDto { + final List indices; + final List values; +} + +static final class RrfDto { + final List ranks; + final Integer k; + final Boolean normalize; +} + +static final class RrfRankItemDto { + final Object rank; // KnnDto wrapped in {"knn":{...}} — needs custom serialization + final Double weight; +} + +static final class SearchSelectDto { + final List keys; +} + +static final class SearchPageDto { + final Integer limit; + final Integer offset; +} + +static final class GroupByDto { + final String key; + @SerializedName("min_k") + final Integer minK; + @SerializedName("max_k") + final Integer maxK; +} + +static final class SearchResponse { + List> ids; + List> documents; + List>> metadatas; + List>> embeddings; + List> scores; +} +``` + +**Serialization challenge:** The `rank` field in `SearchItemDto` must serialize as `{"knn":{...}}` or `{"rrf":{...}}`.
