ps : is it possible to mark the current patch as deprecated or something?
> Optimize queries that check for the existence of a property

> Key: JCR-1064
> 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.patch

> //[EMAIL PROTECTED] 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
