Hi team 👋:skin-tone-2:, I wanted to ask:
I have a query parameter as Chris Schmidt , and I’m querying by first name, last name. However I’m getting results matched just by Chris, and no matches by the lastName, so for example I would get Chris Rogers, Chris Williams etc above Christopher Schmidt, I believe this is because it’s taking it as a whole sentence instead of per word, so my question is
How could I get matches both by Chris and Schmidt 🙌:skin-tone-2:

This behavior is because Typesense first searches for Chris Schmidt and when it doesn’t find a full exact match, it then tries to drop words from the query (configured by drop_tokens_threshold) and searches just Chris and Schmidt.

If you’ve configured first_name to have higher priority (based on order of fields in query_by) it then finds an exact match for Chris and prioritizes those records first in the results.

Also, for shortened version of names specifically, here’s a way to handle those: https://typesense-community.slack.com/archives/C01P749MET0/p1677788106005749

Could you add your example as a comment to this feature request so we can track demand?

Jason Thanks for your quick reply. I understand your explanation, however, even if I set the weights the same & set prioritize exact match to false, it would not take into account Schmidt & return the results for Chris. Do you think there’s a workaround to also take into account the second word when dropping words?

Thanks added this to the Feature request, it would be awesome 🙌:skin-tone-2:

Could you try increasing drop_tokens_treshold: 1000 and set max_candidates: 1000 to see if that helps?
