[whiterabbit1983]

Important

Add metadata_filter to document search requests and functions for filtering by metadata.

• Behavior:
  • Add metadata_filter argument to BaseDocSearchRequest in Docs.py for filtering document searches by metadata.
  • Update search_docs_by_embedding() and search_docs_by_text() in search_docs_by_embedding.py and search_docs_by_text.py to handle metadata_filter.
  • Modify get_search_fn_and_params() in search_docs.py to pass metadata_filter to search functions.
• Models:
  • Update BaseDocSearchRequest in models.tsp to include metadata_filter.
• API Documentation:
  • Add metadata_filter to OpenAPI specifications in openapi-0.4.0.yaml and openapi-1.0.0.yaml.

• Draft comment:
  The metadata_filter parameter is marked as required in the OpenAPI specification. Consider making it optional to allow more flexible API requests.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  The comment is suggesting a design change to make the API more flexible by making 'metadata_filter' optional. This is a valid suggestion as it could improve the API's usability. The comment is directly related to the change made in the diff.
  The comment is speculative in nature, suggesting a design change without concrete evidence that it is necessary. It assumes that making 'metadata_filter' optional is beneficial without context on the API's intended use.
  While the comment is speculative, it does provide a valid point about API flexibility. If the API's design allows for optional parameters, this could be a beneficial change.
  The comment should be kept as it provides a valid suggestion for improving API flexibility by making 'metadata_filter' optional.
