We are experiencing a strange issue. When searching for something on 'book_id' we have 60 records that have a book_id that starts with 'EXAMPLE'. When I perform a search (both on the cloud ui and our build) of 'EXAM', only 4 show up. Most records are 'EXAMPLE[set of numbers]' e.g. 'EXAMPLE001'. If I search for the full exact match term, the record will be found but otherwise I don't get a full list?
We're on v0.23.0.rc62

?max_candidates=1000e
Edward Sparks

05/12/2022, 9:10 AMWhat about searching with
exhaustive_search=truee
Edward Sparks
05/12/2022, 9:11 AMah. that has made a big improvement
Edward Sparks
05/12/2022, 9:11 AMwhere do I find these options to add. And is this something we should always use?
Edward Sparks
05/12/2022, 9:12 AMIt has made the search noticeably slower. Is that normal?

05/12/2022, 9:14 AMYes, so what's happening is this:
When there are a lot of words sharing a prefix, Typesense restricts prefix candidates to a few words because typically it's difficult to guess which word the user is actually looking for so Typesense only looks at top 4. The max_candidates is supposed to increase that to a higher number as you see fit. However, I don't know why it doesn't work for you. This parameter is added only in 0.23 RC.

05/12/2022, 9:16 AMIf there's a way for you to share your dataset (any representative set that reproduces the problem), I can investigate why increasing max_candidates is not working.

05/12/2022, 9:17 AMThat's strange that the max_candidates isn't working for it. We definitely have at least 30 records that start with 'EXAMPLE'
