Right, and it's also the case that certain solr features are coded with the cache in mind (i.e. they will be utilized for a single request for things like highlighting, multi-select faceting, etc. On Fri, Jun 7, 2013 at 3:24 AM, Varsha Rani <varsha.ya...@orkash.com> wrote: > I 'm trying to compare the performance of different Solr queries.

If you are using/testing lucene query syntax, you can just add an additional term that doesn't match anything and then keep changing it... that will prevent the query/filter cache from recognizing it as the same. q=(my big query I'm testing) aaaaab And then next time change the "b" to a "c", etc. Or you could explicitly tell solr not to cache it: http://yonik.com/posts/advanced-filter-caching-in-solr/ q={!cache=false}(my big query I'm testing) -Yonik http://lucidworks.com
