Can someone explain how the

distance_threshold

parameter works in Typesense by default? I expected that when performing a vector search, all documents would be retrieved, even those with minimal relevance to the query. However, it seems that some documents are not included in the results. For instance, when I set

per_page: 100

and

page: 200

, I received results indicating

found: 14,553 out of 21,550

documents on

page: 200

. So

6997

documents are missing from the result. What might be causing this?
