Filters as a variable construct?


I’ve got a RAG application and I am trying to improve retrieval accuracy.

After the user enters their query, I have an LLM question pre-processor which expands and classifies the question type. For now it breaks the question type down into either “tech” (general technology question) or “spec” (specific product question), but eventually I’d like to extract more targeting data from the pre-processor… I’d like to use a different filter for each case.

        #set filters, etc to match search_type
        if search_type == "tech":
            my_filters=(wvc.query.Filter.by_property("file_name").like("EP*") |
            wvc.query.Filter.by_property("file_name").like("ES*") ),

        response = collection.query.hybrid(
            alpha=0.6, #proportion of vector search 1.0 = 100% vector

The above construct fails with:
Argument of type "tuple[_Filters] | _Filters" cannot be assigned to parameter "filters" of type "_Filters | None" in function "hybrid"

Yes, I could absolutely set up different queries for each search type, but that seems like it will get long and messy as I add refinements from the pre-processor.

Is there a programatic way to define filters outside of the collection.query() function call?

hi @Gene_Mc !!

the filter argument will only receive a _Filters parameters or None.

your my_filters is a tuple, so that’s the reason of your issue.

That’s because you have a , and the end of your my_filters variable definition:

my_filters=(wvc.query.Filter.by_property("file_name").like("EP*") |
            wvc.query.Filter.by_property("file_name").like("ES*") )--->,<-------

If you remove that ,, it should work as expected.

Let me know if this helps :slight_smile:

hi @DudaNogueira,

Apologies for raising that…

Yes, it works properly now…sigh…
