Can’t find info on this after browsing the docs and GitHub so asking here. Is there some way to use wildcards when querying by a specific field? As in, any document with some value for the field I’m querying will match. My use case here is a knowledgebase where some documents are tagged, and I need to search for (all or some of) those documents. Another solution would be a way to filter by array length, or something to that effect.

I don't fully understand the question. Could you share a few sample documents along with an example of a query (pseudo code) you'd want to use to fetch them?
