Changelog Entry
Description
This PR improves hybrid search speed if bm_25 weight is 0 (or less) by disabling collection retrieval and bm_25 ranking.
Changed
Disables entire collection retrieval, which is then used to calculate the bm_25 ranking, if the vm_25_weight is 0 or less. If the bm_25_weight is 0 dummy collection results are sent to the query_doc_with_hybrid_search function since they aren't used.
Additional Information
Especially helpful if the collection is large and retrieval takes a lot of time
