Subject Re: solr 5.2.0 need to build high query response

It sounds like you're not doing proper autowarming,
which you'd need to do either with hard or
soft commits that open new searchers.

see: https://wiki.apache.org/solr/SolrCaching#Cache_Warming_and_Autowarming

In particular, you should have a newSearcher event
that facets on the fields you expect to need.

Best,
Erick
