Hi Em, I briefly read the thread. Are you talking about combing of cached clauses of BooleanQuery, instead of evaluating whole BQ as a filter?
I found something like that in API (but only in API) http://lucene.apache.org/solr/api/org/apache/solr/search/ExtendedQuery.html#setCacheSep(boolean) Am I get you right? Why do you need it, btw? If I'm .. I have idea how to do it in two mins: q=+f:text +(_query_:{!fq}id:1 _query_:{!fq}id:2 _query_:{!fq}id:3 _query_:{!fq}id:4)... Right leg will be a BooleanQuery with SHOULD clauses backed on cached queries (see below). if you are not scarred by the syntax yet you can implement trivial "fq"QParserPlugin, which will be just // lazily through User/Generic Cache q = new FilteredQuery (new MatchAllDocsQuery(), new CachingWrapperFilter(new QueryWrapperFilter(subQuery(localParams.get(QueryParsing.V))))); return q; it will use per segment bitset at contrast to Solr's fq which caches for top level reader. WDYT?
