From 8ac5754f0708edd7f9f19655004b61b52fdfbff8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 33/47] feat(firestore): pipeline search (#16469)

Implements Search functionality:

- new `search` stage
- `between` expression (as alias for `And(GreaterThanOrEqual(x),
LessThanOrEqual(y)`)
- `geo_distance` expression (for use in search stages only)
- `Score()` expression  (for use in search stages only)
- SocumentMatches expression (for use in search stages only)

Subject: [PATCH 34/47] feat(firestore): new generic pipeline expressions
 (#16550)

New Expressions:
- offset
- nor
- coalesce
- switch_on
- array_filter
- array_transform
- storage_size

Restructured how custom repr() strings are build, to accommodate
complexities in array_transform

Note: parent and reference_slice will be added in a future PR. More
detailed changes will be needed to support arbitrary collection/database
references; currently only document references are supported

+                on the ``request`` instance; if ``request`` is provided, this

+            retry (google.api_core.retry.Retry): Designation of what errors, if any,

+            timeout (float): The timeout for this request.
+            metadata (Sequence[Tuple[str, Union[str, bytes]]]): Key/value pairs which should be

[bug/issue](https://github.com/googleapis/google-cloud-python/issues)
before writing your code! That way we can discuss the change, evaluate
designs, and agree on the general idea
- [ ] Ensure the tests and linter pass
- [ ] Code coverage does not decrease (if any source code was changed)
- [ ] Appropriate docs were updated (if necessary)

Subject: [PATCH 37/47] chore(firestore): prep for firestore pipelines GA
 (#16549)

Misc changes in prep for GA release of pipelines:

- re-enable releases for firestore
- remove notes about pipelines being in preview
    - added individual beta labels for search/dml classes and methods
- expose options in raw_stage
- renamed Type to PipelineDataType
- moved helper classes (options, enums) into pipeline_types
- expose pipeline classes in top-level \_\_init__.py
