Subject [jira] [Updated] (JCR-2959) SQL2 QueryEngine should use Lucene for sort
Date Fri, 12 Aug 2011 15:01:34 GMT

     [ https://issues.apache.org/jira/browse/JCR-2959?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Parvulescu updated JCR-2959:
---------------------------------

    Priority: Minor  (was: Major)
     Summary: SQL2 QueryEngine should use Lucene for sort  (was: SQL2 "order by" can't be
used - QueryEngine should use Lucene for sort instead of Collections.sort (line 327))

I've changed the name, it was a bit too inflammatory :)

I agree with the idea that we should investigate native lucene search, with custom hooks into
JR for fetching Node data.

> Currently all SQL2 queries with "order by" expression are sorted with Collections.sort
- which is slow and very bad if there are lots of hits. Lucene should be used for sorting
hits instead.
