Christine Poerschke commented on SOLR-13289:
--------------------------------------------

{quote}{quote}would or wouldn't a minExactHits=100 request make use of a 
minExactHits=1000
{quote}
It wouldn't. Right now, it's just using equal. We could improve this for sure, 
that said, I'm wondering how useful that would be in practice? like, people 
doing the same request in the same index with different minExactHits. While 
certainly could happen, I'm not sure how common that is.
{quote}
I agree, say {{minExactCount=100}} and {{minExactCount=1000}} on the same index 
might be uncommon but a query with a {{minExactCount=}} restriction being able 
to use a cache entry from a query without a {{minExactCount=}} restriction 
might be more interesting. Anyhow, I've speculatively opened 
[https://github.com/apache/lucene-solr/pull/1530] – though perhaps a new ticket 
would be clearer since this one is now closed.
