Has anyone used the "Flexible Query Parser" (https://issues.apache.org/jira/browse/LUCENE-1567) in Solr? I'm just starting to look at it for the first time and was wondering if it is something that can be dropped into Solr fairly easily, or if more extensive changes are needed. I thought perhaps someone had already done this, but I couldn't find anything in the Solr bug tracker.
