[jira] Commented: (SOLR-2052) Allow for a list of filter queries and a single docset filter in QueryComponent

    [ https://issues.apache.org/jira/browse/SOLR-2052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971715#action_12971715 ] 

Jonathan Rochkind commented on SOLR-2052:
-----------------------------------------

Very interested in this functionality -- but only if it could be combined with traditional fq's too. Would this patch allow a bit-filter as one filter, with additional ordinary fq's being additional filters on top, as well as an ordinary 'query' etc?  If so, definitely very interested.

> SolrIndexSearcher.QueryCommand allows you to specify a list of filter queries or a single filter (as a DocSet), but not both.  This restriction seems arbitrary, and there are cases where we can have both a list of filter queries and a DocSet generated by some other non-query process (e.g., filtering documents according to IDs pulled from some other source like a database.)
> Fixing this requires a few small changes to SolrIndexSearcher to allow both of these to be set for a QueryCommand and to take both into account when evaluating the query.  It also requires a modification to ResponseBuilder to allow setting the single filter at query time.
> I've run into this against 1.4, but the same holds true for the trunk.
