I was wondering if there was a roadmap for the development of the vector_search function: vector_search function | Databricks Documentation

Specifically, I was wondering if / when the following limitations may be lifted:

• Querying DIRECT_ACCESS index types are not supported.
• Input parameters filters_json are not supported.
• Hybrid keyword-similarity search is not supported using vector_search().

We are currently developing a solution which requires the use of a direct access vector store and batch similarity searches, in which we require the use of filters and preferably hybrid search (though hybrid search is more of a nice to have for now).

Currently our solution uses an async function to do this, but this takes a while:

from databricks.vector_search.client import VectorSearchClient

index.similarity_search(
	query_text= q,
	num_results= k,
	query_vector= embedded_query,
	filters= {"document_id": document_id_filter},
	query_type= "hybrid"
)
