SPLIT with matches / not matches

Hello everybody,
I'm trying to split apache log data into two output sets, one for all
uris that match a certain criterie and one for uris that don't match a
certain criteria.
I've been trying 

SPLIT list INTO downloads IF uri matches '/downloads/.*\\.exe', pages if
(NOT uri matches '/downloads/.*\\.exe');

but this doesn't seem to do the trick (downloads is fine, but pages
contains the downloads too :/)
Any hints on how to do this?

Johannes

I suppose there are some issues with split. It would be ideal to have your input set, but did you try with 2-step filter operation instead of split and got the correct answer?If not, I would look at the regex expr.
