Hi, using filterQuery(fq) is more efficient because SolrIndexSearcher will make use of filterCache and in your case it returns entire set from the cache instead of searching from the entire index.

Since we are not interested in scoring this results, I was thinking that maybe this should be performed as a filterQuery (fq="brand:xxx"), and in that case I guess I shall be using a wildcard for the query (q="*:*"), as I'd get an NPE on the missing parameter otherwise. Does something like this even make sense? Is there a proper way to do a query like this, or is the normal route of using q=brand:xxx already the best way? Thanks in advance for any answer. -- blog en: http://www.riffraff.info blog it: http://riffraff.blogsome.com
