Subject [jira] [Commented] (OAK-1654) Composite index aggregates
Date Tue, 01 Apr 2014 20:15:15 GMT

    [ https://issues.apache.org/jira/browse/OAK-1654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13956972#comment-13956972

Alex Parvulescu commented on OAK-1654:

thanks Thomas, there were some issues with the impl so I had to tweak it a bit. Also following
the example I added a new Cursor that concatenates more Cursors.
I managed to work around the cost issue as well now, so everything should be fine.

I pushed the code in with rev http://svn.apache.org/r1583771

If there's anything I left out, please let me know.

> This is a followup for what is still missing from OAK-828: composite aggregates.
> This covers 2 parts:
>  - when searching for 2 tokens that can be present on 2 different nodes, the common aggregated
parent doesn't show up
>  - when adding together multiple contains clauses on different hierarchy levels: now
the lucene index simply returns an infinite cost.
