Marcel Reutegger resolved JCR-967.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 1.4

> tree or not.

Ok, fair enough.

Based on your ASF license grant on the patch I added a license header to PathQueryNodeTest, which was missing. I also added JavaDoc to the new method SearchIndex.getIndexReader(boolean) and opened up the visibility to protected.

Thanks a lot for your work!

> Right now every time a query is executed the index of the current workspace as well as the index of the "jcr:system" tree is searched. A lot of queries are not searching in the "jcr:system" tree at all therefore it should be checked if the query contains paths that include "jcr:system". There are two relevant nodes in the query tree to find that out:
> - what's the first location step and does it include the jcr:system tree? I think that's an easy one.
> - does the query contain a jcr:deref node? If there is an intermediate result of a query may dereference into the jcr:system tree. 
> This should notably speed up query execution if you are working extensively with versioning.
