Extract metada from query and use it for pre-filtering in Weaviate

[shanumas]

I want to extract "title preference" from user query. For example, user is interested in documents for which
the title has "usa" in it.

I want to extact this during using llm during the query phase and use it for pre-filtering in weaviate. How can
I do this ?

I see that the metadata_extractor is attached in the ingest.py . But I want to use metadata_extractor during query
phase also.

@shanumas check out this section of langchain docs https://python.langchain.com/v0.2/docs/how_to/query_constructing_filters/
