Marcel Reutegger commented on JCR-1659:
---------------------------------------

Comments on patch:

- JackrabbitIndexSearcher only contains rearranged imports
- We should rather use PathFactory.getParentElement() instead of defining a new name
- It seems LuceneQueryBuilder.visit(LocationStepQueryNode,Object) does not respect includeDescendants() for parent name
- QueryFormat probably has to be adapted to support round tripping abstract query tree to XPath/SQL
- Test case are missing

> We need to be able to do the following inside our application:
> /blogs/blog/entry[@title='Jackrabbit' or ../@author='Dan Diephouse']
> The example is contrived, but the need is real. Neither "../" or "parent::" seems to be supported currently. See this thread for the original discussion: http://markmail.org/message/dyxnobdwd7sofmes
