Description

We would like to enable customized grouping in Lucene/Solr. Our need is to allow grouping by hamming distance of a text field. We started implementing this idea through editing several Lucene classes (Grouping, AbstractTermFirstPassGroupingCollector and AbstractTermSecondPassGroupingCollector) so that they receive custom logic to use for grouping.
