Subject: [PATCH] Add database indexes to frequently queried model fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add db_index=True to Question.filename and Question.Hash
- Add db_index=True to Course.name and Course.university
- Add db_index=True to UploadedFile.filename

These indexes will significantly improve query performance for search
operations and file lookups, especially as the database grows. The
indexed fields are frequently used in filter() and get() operations
throughout the codebase.
