> When {{rows=0}}, and for {{MatchAllDocsQuery}} and {{ConstantScoreQuery}} (and possibly others?), it is possible for {{SolrIndexSearcher.getDocListC(QueryResult, QueryCommand)}} to create a DocList directly from {{filterCache}} DocSets -- similar to {{useFilterForSortedQuery}}, but without actually sorting. 
> This results in significant benefits for high-recall domains, including the common (and commonly-cached) use-case of {{q=\*:*}} and {{fq}}, facets, etc.
