New edismax param mm.autoRelax to aid in fixing the dismax/edismax stopwords mm issue

    XMLWordPrintableJSON

Details

    Description

      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.
