--- Comment #42 from Sebastian Trueg <sebastian trueg de>  2011-01-20 17:04:06 ---
SVN commit 1215973 by trueg:

Backport:
* Fixed the handling of quotes and keywords such as "AND", "OR", and "NOT" in
LiteralTerm.
  Now correct bif:contains or regex filters are created for values.
* Made the query parser merge LiteralTerms into a single one to improve query
performance.
  While merging two LiteralTerms into one does not yield the exact same query
(when merged
  both literal tokens need to appear in the same property value while with
separate LiteralTerms
  the tokens can appear in different properties) it should cover close to all
typical use cases
  while increasing the performance significantly and getting rid of the nasty
"Virtuoso goes
  crazy when I use KRunner" bug.

CCBUG: 246678
