Hi
Sorry, I don't understand one point from this great software.
I'd like to do this:
1. When I have in a document the word <Gartenhaus> (I use my german example), then I want add a tag for exactly the whole string.
2. When I have in a further condition add a tag by the word <Garten>, so this shouldn't add a tag to the example above (<Gartenhaus>). Also this condition should only compare the whole string, not only a part of them.
At the moment, my second condition add also a tag to the first example <Gartenhaus>.
Can somebody help me please? Thanks a lot.
