Subject [jira] [Commented] (LUCENE-4765) Multi-valued docvalues field
Date Tue, 12 Feb 2013 11:29:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13576553#comment-13576553
] 

Robert Muir commented on LUCENE-4765:
-------------------------------------

some progress:
* 4.2, assertingcodec, checkindex, etc are working
* fieldcache.getDocTermOrds returns SortedSetDocValues (and from IR if you indexed them)
* join/ and grouping/ are ported over to the new API

next step:
* simpletext and disk codecs.

> The general idea is basically the docvalues parallel to FieldCache.getDocTermOrds/UninvertedField
> Currently this stuff is used in e.g. grouping and join for multivalued fields, and in
solr for faceting.
