Hi there!
We've been having some trouble getting min\_score to work.
We have two types. There is user\_meta, the parent index type. There is also
the child index, user\_perk (specified below.)
The query returns both the right documents and accurate scores for those
documents, but when I add a min\_score \>= 1, it returns no data.
Another weird behavior is that changing the boost value in constant\_score
does not change the score that is returned. For example, if I have a boost
value of 1 and a document that has a score of 29, that document will also
have a score of 29 if I set a boost value of 0.1.
Very confused here. Are we doing something wrong?
Thanks!
Jieren
