Perhaps you should try some spelling variations:
methode iv » methoden iv, methode im, methode ii
methode v » methode vi, methode 2, methode 3
iv bayers » iv bayes, v bayers, iv bars
v bayes » iv bayes, v bayers, _ bayes

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( methode v bayes / gtt ) OR ( methode iv bayers / gtt )).
• Adding a wildcard symbol may retrieve word variants: (( methode v bayes / gtt ) or ( methode iv bayers / gtt ))*.
