I have Solr 4.2.1 and run them as SolrCloud. When I do a search on SolrCloud as like that:
ip_of_node_1:8983solr/select?q=*:*&rows=10000 and when I check admin page I see that: I have 5 GB Java Heap. 616.32 MB is dark gray, 3.13 GB is gray. Before my search it was something like: 150 MB dark gray, 500 MB gray. I understand that when I do a search like that, fields are cached. However when I look at other SolrCloud nodes' admin pages there are no differences. Why that query is cached only by the node that I run that query on?
