I am unsure what you mean when you say /how big a filter query can be ? /. Do you mean how long can a single filter query can be or a limit on number of filter queries that can be put?
For the former you may want to visit the maxBooleanClauses in your solrconfig. Try the link: he tottp://wiki.apache.org/solr/SolrConfigXml#The_Query_Section <http://wiki.apache.org/solr/SolrConfigXml#The_Query_Section> Am not too sure if there is a limit on the number of filters that you can put in a query. In either case, I think the length is also dependent on your webcontainer config settings i.e. the max url length that it can accept. Also you may have to revisit your filterCache settings. There is no optimal number for the filterCache, you may have come to a number after trying various combinations. http://wiki.apache.org/solr/SolrCaching#filterCache <http://wiki.apache.org/solr/SolrCaching#filterCache> -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Filter-Query-tp4085807p4085832.html Sent from the Solr - User mailing list archive at Nabble.com.
