After reading a little bit more and finding googles patent [arnoldit.com...] , i finally found this blog entry Matt Cutts already talked about too [googleblog.blogspot.com...]
In the end, it says "You can also turn off a synonym for a specific term by adding a "+" before it or by putting the words in quotation marks."
Now guess what happens i do that on the terms we have used to rank good.... Yeah, rankings are just like they used to be when switching off their synonym stuff.
In their patent they describe how they insert different synonyms, and that they calculate a number for "how close" the synonym is. However, i can't see the latter in the serps
