Hello, after several fits and starts, I'm not able to do precisely what I'm intending and rather than spending a ton of time working this out I thought I would ask for some help. I also could not find the answer in searching through forum spreads so forgive me if this is a duplicate.
I would like to find Semitic roots (I say Semitic because I would want to also do this for Syriac and Aramaic and use the answer here as a template) that only occur in one stem, e.g., the Pi''el. I attempted this by searching for a wildcard verb in the Pi''el and then an <AND> with a "NOT" (~) selected with every other stem, which is not only extremely inelegant but also does not seem to be returning correct results.
Many thanks in advance for your help.
