Shawn Heisey commented on SOLR-1223:
------------------------------------
bq. I'd rather see a new filterQuery type like ofq than being stuck with the
current options. Nested filterQueries including variables would obviously be
the most flexible solution, but imho having two different filter types would
add enough benefit in the meantime.
I see that someone else had the same idea a long time before I did. I just
brought this up on the solr-user list a few days ago, but I couldn't think of a
good parameter name. The parameter name I came up with (fqu, filter query
union) is not as good as ofq.
I like Brian and Frederik's idea.
> Query Filter fq with OR operator

> Key: SOLR-1223
> URL: https://issues.apache.org/jira/browse/SOLR-1223
> Project: Solr
> Issue Type: New Feature

> Priority: Minor

> See this
> [issue|http://www.nabble.com/Query-Filter-fq-with-OR-operator-td23895837.html]
> for some background. Today, all of the Query filters specified with the
> fq parameter are AND'd together.
> This issue is about allowing a set of filters to be OR'd together (in
> addition to having another set of filters that are AND'd). The OR'd
> filters would of course be applied before any scoring is done.
> The advantage of this feature is that you will be able to break up complex
> filters into simple, more cacheable filters, which should improve performance.
