[jira] [Created] (SOLR-4938) Solr should be able to use Lucene's BlockGroupingCollector for field-collapsing

-------------------------------------

             Summary: Solr should be able to use Lucene's BlockGroupingCollector for field-collapsing
                 Key: SOLR-4938
                 URL: https://issues.apache.org/jira/browse/SOLR-4938
             Project: Solr
          Issue Type: New Feature
    Affects Versions: 4.3.1
            Reporter: Tom Burton-West
            Priority: Minor


In Lucene it is possible to use the BlockGroupingCollector  for grouping in order to take advantage of indexing document blocks: IndexWriter.addDocuments().   With SOLR-3076 and SOLR-3535, it is possible to index document blocks.   It would be nice to have an option to use the BlockGroupingCollector with Solr field-collapsing/grouping.
