Bug 6510 - [REVISED] Sort by in intranet search alters search and number of hits

This patch uses .*? instead of .*

To test:
- In advanced search in the intranet choose Author as the search index
- Do a search for an author, check the number of hits
- Choose another value than the default from Sort by
- Check that the number of hits is the same as for the original search, once
  the hits have been re-ordered
