I was reading that URL -> http://wiki.apache.org/solr/FilterQueryGuidance
In "Stray bits" paragraph, "Memory consumption per filter field value is not a great concern here as the filterCache typically (perhaps always) stores only bit vectors, each bit representing a boolean to signal whether or not the document in question is a member of the set matching the filter specification. Document reference is implicit by each bit's position in the vector; this is by virtue of the fact that Solr's internal document IDs (which are different from the document IDs the user may assign via the <uniqueKey> in schema.xml) are a sequence of consecutive integers." Below is part of my schema.xml. =========================== <uniqueKey>id</uniqueKey> <field name="id" type="string" indexed="true" stored="true" required="true" /> =========================== Type of id field is "string". I think the setting cause difference result in q and fq query.
