Could it be that "<ais-refinement-list attribute="marketing_claims" operator="*and*" />" does not work as expected? If I select 2 refinements I get more results back, even though it should be less. Also if I use "or" or "and" I can see the same query being generated by the typesense-instantsearch-adapater

Looks like we might have to explicitly handle the operator parameter in the adapter. I'll take a look shortly.

done thank you!
