> 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
