LangChain Community: AzureCosmosDBNoSqlVectorStore: Improvements to the Hybrid Search

[aayush3011]

Improvements to Hybrid Search

• Adding support for multiple text fields to be used for Full Text Search

• Adding support for VectorStoreRetriever

• Updated test cases for the above

• Updated the integration notebooks

• Add tests and docs: If you're adding a new integration, please include

  1. a test for the integration, preferably unit tests that do not rely on network access,
  2. an example notebook showing its use. It lives in docs/docs/integrations directory.

• Lint and test: Run make format, make lint and make test from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/

Additional guidelines:

• Make sure optional dependencies are imported within a function.
• Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
• Most PRs should not touch more than one package.
• Changes should be backwards compatible.
• If you are adding something to community, do not re-import it in langchain.

If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, ccurme, vbarda, hwchase17.

@baskaryan , can you please review the PR. Can you also please look into the one lint pipeline that is failing, I am not sure what is the issue there.

There are lots of breaking changes in this PR. Ideally, any user code that was working before this change will continue to work after. Is that possible?
