Marcel Reutegger resolved JCR-1365.
-----------------------------------
Resolution: Fixed
Fix Version/s: 1.5
Implemented more performance optimizations. If the last location step is a
child or descendant-or-self axis with a node test that matches any node, the
implementation now uses context query result in conjunction with the regular
API to find the matching nodes.
This again gives a performance improvement of a factor of 7 compared to 'series
2' and still a factor of 2 compared to 'series 3', where the cacheSize was
increased significantly.

> To resolve the * step the LuceneQueryBuilder currently creates a
> MatchAllQuery and checks every node for a foo ancestor. Instead, it should
> search for bar nodes and check for foo ancestors with at least one arbitrary
> hierarchy level in between.
