Enable Filters in MongoDB Vector Search Retriever

[ghondar]

Summary:

This pull request introduces changes that enable the use of filters in the MongoDB vector search retriever, similar to how it’s done in Pinecone.

Description:

• These changes will allow the implementation of filters in the MongoDB Vector Search Retriever, aligning with the capabilities provided by Pinecone.
• When creating an Atlas Vector Search to index the embedding field, it’s important to also add the filters you want to use, as demonstrated in the MongoDB documentation: MongoDB Atlas Vector Search - Create Index.

Points to consider:

• Ensure that when configuring the Atlas Vector Search for your application, you define both the embedding field and any necessary filters during index creation, as described in the documentation.
