Subject [jira] [Updated] (LUCENE-3602) Add join query to Lucene
Date Sun, 05 Feb 2012 21:37:59 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3602?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Martijn van Groningen updated LUCENE-3602:
------------------------------------------

    Attachment: LUCENE-3602-3x.patch

Attached updated version of query time joining for 3x branch. Instead of doing a binary search
for each term comparison it seeks / iterates forward. It can't do seeking like we do in trunk,
so it isn't as fast as in trunk. However I do think this can be committed to at least have
query time join support in 3x. Back porting per segment filtering and the MTQ that is in trunk
is quite some work...

Lucene.
