Proposal for Enhanced Functionality in Langchain Milvus Integration

[mohit19906]

Currently, Langchain's functionality permits loading chunks into Milvus and retrieving them using a question. However, Milvus has the potential for much more extensive uses. It would be beneficial to see these additional capabilities incorporated into the Langchain integration. Some of these features include:

1 - The ability to add multiple user-defined columns in a collection.
2 - The capability to retrieve a document using hybrid search parameters.
3 - The option to apply various indexing methods when creating a collection.

I encourage you to enhance the Langchain Milvus integration by adding these extra functionalities.

I really need a "Hybrid Search" solution in Langchain Milvus. If it exists, I would appreciate an example.
