Or remove the filterCache config option from your solrconfig.xml if you
really don't want any caching of any filter queries.

Fnrakly though: that's throwing the baby out with the bath water -- just 
because you are updating your index super-fast-like doesn't mean you 
aren't getting benefts from the caches, particularly from commonly 
reused filters which are applied to many qureies which might get 
executed concurrently -- not to entnion that a single filter might be 
reused multiple times within a single request to solr.

disabling cache *warming* can make a lot of sense in NRT cases, but 
eliminating caching alltogether rarely does.
