Thanks Erick. I see the above pattern only at the time of commit.
I have many fields (like around 250 fields out of which around 100 fields are dynamic fields and around 3 n-gram fields and text fields, while many of them are stored fields along with indexed fields), will a merge take a lot of time in this kind of case, I mean is it CPU intensive because of many dynamic fields or because of huge data? Also, I am doing a hard commit for every 5 minutes and open-searcher is true in my case. I am not doing soft-commit. And below are the configurations for filter, query and document caches. Should I try reducing initialsize? <filterCache class="solr.FastLRUCache" size="2048" initialSize="512" autowarmCount="0"/> <documentCache class="solr.LRUCache" size="2048" initialSize="512" autowarmCount="0"/> <queryResultCache class="solr.LRUCache" size="2048" initialSize="512" autowarmCount="0"/> -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
