             Summary: Support relative property based query by transforming the path
                 Key: OAK-4906
                 URL: https://issues.apache.org/jira/browse/OAK-4906
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: lucene
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra
            Priority: Minor
             Fix For: 1.6


PropertyIndex supports query like below

{noformat}
/jcr:root//*[jcr:content/@keywords]
{noformat}

For such query _keywords_ property is indexed and the as part of Cursor returned for the query the path is transformed to return the parent path if the parent node is _jcr:content_

Currently LucenePropertyIndex supports indexing relative properties wrt base node like {{jcr:content/metadata/status}}. Here it would index the relative property by refererring to its relative name. 

To simplify switch to LucenePropertyIndex (as part of hybrid index support) LucenePropertyIndex should also support for such queries where property index definition only specifies indexing _keywords_ but the query is using a relative property. So LucenePropertyIndex should

# First check if it has a property definition for _jcr:content/keywords_
# If not check if the indexingRule is for nt:base
# If yes check if it has property definition for _keywords_
# If yes then use the index to evaluate the query and return transformed result

LucenePropertyIndex already do such transformations for fulltext constraints. With this we extend that support for property restrictions also
