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
//[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
