Hi We are using Solr 6.6.2 version with 10g of memory (2 slaves and 1 master ) allocated to each and have around 300000 docs. Our queries have combinations of q, fq and facets with grouping enabled...
We have enabled filter cache and query result cache with 2048 entries. Recently we performed a load of only 400 users with 1000 unique queries getting repeated within users Cpu usage on solr slaves was around 300%... plus queries were not getting served from cache... We can see inserts in filter cache and hit ratio is also increasing but query result cache is not getting any inserts Can you please help in explaining why there are no jnserts in query redult cache even though there are repetitive queries
