Subject [jira] Commented: (JCR-1064) Optimize queries that check for the existence of a property
Date Sun, 23 Sep 2007 20:32:51 GMT

    [ https://issues.apache.org/jira/browse/JCR-1064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12529762
] 

Ard Schrijvers commented on JCR-1064:
-------------------------------------

I have done the tests with old style indices and remove the parent handler index or the workspace
index, tried with new style indices, all work as they should.

Also like the replacement of the IndexFormatVersion.version from String to int, to make future
versions number possible. So, AFAICS, everything seems to work how it should. 

Thanks both for all the help regarding this issue.

> //*[@mytext] is transformed into the org.apache.jackrabbit.core.query.lucene.MatchAllQuery,
that through the MatchAllWeight uses the MatchAllScorer.  The calculateDocFilter() in MatchAllScorer
 does not scale and becomes slow for growing number of nodes. 
> Solution: lucene documents will get a new Field:
> public static final String PROPERTIES_SET = "_:PROPERTIES_SET".intern();
> that holds the available properties of this document. 
> NOTE: Lucene indices build without this performance improvement should still work and
fall back to the original implementation
