> As discussed here http://search-lucene.com/m/Wr7iz1a95jx and here http://search-lucene.com/m/Yne042qEyCq1 and here 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.
