Context

The chat-gpt-retrieval integration has a TODO to support the `create_search_index` operation. pymongo supports using the method, however, our integration work has not formalized the best approach to implementing support across all integrations.

Definition of done

Vector search index creation can occur from the chat-gpt-retrieval code.

Pitfalls

Increased complexity and potential confusion that could stem from.
