Jan Høydahl commented on SOLR-3085:
-----------------------------------
Due to popular demand, I committed the {{mm.autoRelax}} logic to trunk only,
for people to play with. After some broader exposure there we can consider
porting to 5.x.
The {{mergeStopwords}} idea is spun off into SOLR-7862.

> http://search-lucene.com/m/RfAp82nSsla DisMax has an issue with stopwords if
> not all fields used in QF have exactly same stopword lists.
> Typical solution is to not use stopwords or harmonize stopword lists across
> all fields in your QF, or relax the MM to a lower percentag. Sometimes these
> are not acceptable workarounds, and we should find a better solution.
