Greetings, I'm wondering if somebody would please explain why SolrIndexSearcher.java enforces mutual exclusion of filter and filterList (e.g. see: https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java#L2039 )
For a custom application we have been using this functionality successfully and I have been maintaining patches against base releases up from 1.4 through 3.6.1 and am now finally looking at 4.0. Since I am yet-again revisiting this custom patch, I am wondering why this functionality is prevented out of the box - for two reasons really: 1) It would be great if I didn't have to maintain a custom internal branch of solr for this tiny little change 2) I am worried that the purposeful prevention of this functionality implies there is a downside to doing this. Is there a downside to utilizing both a DocSet based filter and query based filterList? If not, once I migrate this patch to 4.0 what would be the best way to get this functionality incorporated into the base? For additional info, you may find the now-2-year-old issue with patches addressing this up through 3.6.1 here: https://issues.apache.org/jira/browse/SOLR-2052 Any insight appreciated as always, Aaron
