: it's quite long but this request uses both faceting and grouping. If I : remove the grouping then the cache is used. Is this a normal behavior or : a bug?
I believe that is expected -- i don't think grouping can take advantage of the queryResultCache because of how it collects documents. there is however a "group.cache.percent" option tha you might look into -- but i honestly have no idea if that toggles the use of queryResultCache or something else, i havn't played with it before... https://wiki.apache.org/solr/FieldCollapsing#Request_Parameters -Hoss
