A 2nd question: while watching these stats I noticed something else weird with the queryResultCache. It seems that inserts to the queryResultCache depend on the number of rows requested. For example, an initial request (solr restarted, clean cache, etc) with rows=10 will result in a insert. A 2nd request of the same query with rows=1000 will result in a cache hit. However if you reverse that order, starting with a clean cache, an initial request for rows=1000 will *not* result in an insert to queryResultCache. I have tried various increments--10, 100, 200, 500--and it seems the magic number is somewhere between 200 (cache insert) and 500 (no insert). Can someone explain this?
Perhaps it's this setting in the <query> section of solrconfig.xml? <queryResultMaxDocsCached>200</queryResultMaxDocsCached> See SOLR-291. Shawn
