Willi Goesgens c1d0f8bccc SortIndex: as long as the Index superseeds the sort critereon its still a full match. 2014-09-01 18:29:09 +02:00
Willi Goesgens cd29afd88f Fix pattern to index matcher 
- if the number of match patterns is zero, this is not a match at all.
  - if the number of condition is unequal match pattern to a match pattern this isn't a full match.
