Smart Folder Problem

[Rand72889]

My case: having a group folder for each topic.
Problem: got the idea to use a smart folder for each group but the problem is now that i want a smart folder
that is only getting articles of ONE specific group (possible and working fine).
I want that it parses the group for words - Word1 OR Word2 in the article text AND the headline.
To do so (and not searching all folders) i have to select “match all criteria”. but the i cannot use it as an OR operator!

Version 3.0.3

Any solution ?
Thanks
