Subject [jira] [Commented] (SOLR-2526) Grouping on multiple fields
Date Wed, 18 May 2011 20:14:47 GMT


Michael McCandless commented on SOLR-2526:

I think LUCENE-3099 could make this possible, by allowing subclasses to define arbitrary group
keys per document.  Today the grouping module is "hardwired" to use BytesRef (pulled from
FieldCache of a single-valued indexed field) as the group key, but really it should be able
to be any key.
