Marcel Reutegger commented on JCR-1064: --------------------------------------- > IndexFormatVersion now contains the logic to decide which format version an > index uses > (MultiIndex shouldn't know which FieldNames are used). good point... > 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-1064-2.patch, JCR-1064-2.patch, JCR-1064-2.patch, > JCR-1064-2.patch, JCR-1064-3.patch, JCR-1064-4.patch, JCR-1064-DEPR.patch > > > //[EMAIL PROTECTED] is transformed into the > org.apache.jackrabbit.core.query.lucene.MatchAllQuery, that through the > MatchAllWeight uses the MatchAllScorer.
