Subject [jira] Created: (JCR-1064) Optimize queries that check for the existence of a property
Date Wed, 15 Aug 2007 13:49:30 GMT
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


//*[@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
