Subject [jira] Commented: (JCR-1064) Optimize queries that check for the existence of a property
Date Sat, 25 Aug 2007 07:07:35 GMT

    [ https://issues.apache.org/jira/browse/JCR-1064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12522724

Bertrand Delacretaz commented on JCR-1064:

>> ...ps : is it possible to mark the current patch as deprecated or something?
> I prefer to just keep the attached patches to have a history on what was discussed...

Just upload the patch again with the same filename - JIRA then greys out older versions but
keeps them available, and shows their time and date when hovering the mouse over the names.
See SOLR-69 for example.

>                 URL: https://issues.apache.org/jira/browse/JCR-1064
>             Project: Jackrabbit
>          Issue Type: Improvement
>          Components: indexing
>    Affects Versions: 1.3.1
>            Reporter: Ard Schrijvers
>            Priority: Minor
>             Fix For: 1.4
>         Attachments: JCR-1064-2.patch, JCR-1064-DEPR.patch
> //*[@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
