Each of these is essentially a map where filterCache: key: the filter query value: a bitmap of docs that satisfy the clause, i.e. maxDoc/8
Note, I'm cheating a little here, this is the max size of each entry. queryResultCache: key: the query, probably the whole thing value: an array of integers queryResultWindowSize long (see solrConfig.xml for queryResultWindowSize)..
