Kmail regex searches

[Colin Close]

Hi,
I wonder if you can help me? I have been trying to clean up a large mail collection which has mega quantities of spam. One search that I am trying to perform is to search for percentages.
The form [0-9][0-9]% does not seem to work..the same construct in Thunderbird works fine. I have no explanation for this other than maybe in Kmail some characters may need escaping. Any help gratefully received.
