Perhaps you should try some spelling variations:
"methode vi bavel / gtt" » "methoden vi bavel / gtt", "methode 2 bavel / gtt", "methode 3 bavel / gtt", "methode 2i bavel / gtt", "methode 3i bavel / gtt", "methode 4i bavel / gtt", "methode van bavel / gtt", "methode vi based / gtt", "methode vi baked / gtt"
"methode von bavel / gtt" » "methode van bavel / gtt", "methode von babel / gtt", "methode von gavel / gtt", "methode 2on bavel / gtt", "methode 3on bavel / gtt", "methode 4on bavel / gtt"
"methode v bavel / gtt" » "methode 2 bavel / gtt", "methode 3 bavel / gtt", "methode 4 bavel / gtt", "methode van bavel / gtt", "methode v bavula / gtt"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"methode von bavel / gtt\") OR (\"methode vi bavel / gtt\"))) OR (\"methode v bavel / gtt\"))".
• Removing quotes may allow a broader search: (((( methode von bavel / gtt ) OR ( methode vi bavel / gtt ))) OR ( methode v bavel / gtt )).
• Adding a wildcard symbol may retrieve word variants: (((("methode von bavel / gtt") OR ("methode vi bavel / gtt"))) OR ("methode v bavel / gtt"))*.
