> {{LucenePropertyIndex}} currently uses unique PathCursor [1] due to which the cursor would maintain an in memory set of visited path. This might grow big if result size is big and cursor is traversed completely.
> As with current impl the path would not be duplicated we can avoid using unique cursor
