Jan Høydahl updated SOLR-2058: ------------------------------ Attachment: SOLR-2058-and-3351-not-finished.patch Attaching a patch doing also some ps2/ps3 stuff, adding more tests etc, but it's not finished. Unfortunately it's big partly due to whitespace differences > Adds optional "phrase slop" to edismax "pf2", "pf3" and "pf" parameters with > field~slop^boost syntax > ---------------------------------------------------------------------------------------------------- > > Key: SOLR-2058 > URL: https://issues.apache.org/jira/browse/SOLR-2058 > Project: Solr > Issue Type: Improvement > Components: query parsers > Environment: n/a > Reporter: Ron Mayer > Priority: Minor > Fix For: 4.0 > > Attachments: SOLR-2058-and-3351-not-finished.patch, SOLR-2058.patch, > edismax_pf_with_slop_v2.1.patch, edismax_pf_with_slop_v2.patch, > pf2_with_slop.patch > > > http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201008.mbox/%3c4c659119.2010...@0ape.com%3E > {quote} > From Ron Mayer <r...@0ape.com> > ... my results might be even better if I had a couple different "pf2"s with > different "ps"'s at the same time.
