I have a number of items within the Summary "REG-KLD-xxx" where xxx is a number.
If I set the search to: Summary ~ "REG" it will find the items.
If I set the search to: Summary ~ "REG-" it will find the items.
If I search for: Summary ~ "REG-KLD", no items are found.
If I search for: Summary ~ "REG-K", no items are found.
If I search for: Summary ~ "REG-K*", no items are found.
"-" is no forbidden sign as far as I know.
What am I doing wrong?
