Hello,
It seems Solr is caching when facting even with fq={!cache=false}*:* specified.
This is what I am doing on Solr 4.10.0 on jre 1.7.0_51.
Query 1) No cache in filterCache as expected
http://localhost:8983/solr/collection1/select?q=*:*&rows=0&fq={!cache=false}*:*
http://localhost:8983/solr/#/collection1/plugins/cache?entry=filterCache
confirms this.
Query 2) Query result docset cached in filterCache unexpectedly ?
http://localhost:8983/solr/collection1/select?q=*:*&rows=0&fq={!cache=false}*:*&facet=true&facet.field=foobar&facet.method=enum
http://localhost:8983/solr/#/collection1/plugins/cache?entry=filterCache shows
entry of item_*:*: org.apache.solr.search.BitDocSet@66afbbf cached.
Suggestions why or how this may be avoided since I don't want to cache anything
other than facet(ed) terms in the filterCache (for predictable heap usage).
The culprit seems to be line 1431 @
http://svn.apache.org/viewvc/lucene/dev/tags/lucene_solr_4_10_2/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java?view=markup
Thanks.
