Perhaps you should try some spelling variations:
"methode van bavel / gtt" » "methode von bavel / gtt", "methode vii bavel / gtt", "methode vom bavel / gtt", "methode 2an bavel / gtt", "methode 3an bavel / gtt", "methode 4an bavel / gtt"
"methode vi bavel / gtt" » "methoden vi bavel / gtt", "methode von bavel / gtt", "methode 2 bavel / gtt", "methode 2i bavel / gtt", "methode 3i bavel / gtt", "methode 4i bavel / gtt", "methode vi based / gtt", "methode vi baked / gtt", "methode vi bases / gtt"
"methode 2i bavel / gtt" » "methode 2 bavel / gtt", "methode 23 bavel / gtt", "methode 29 bavel / gtt", "methode 2 pavel / gtt", "methode 24 pavel / gtt"
"methode v bavel / gtt" » "methode 2 bavel / gtt", "methode 3 bavel / gtt", "methode 4 bavel / gtt", "methode v bavula / gtt"

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 van bavel / gtt") OR ("methode vi bavel / gtt"))) OR ("methode 2i bavel / gtt"))) OR ("methode v bavel / gtt")).
• Removing quotes may allow a broader search: (((((( methode van bavel / gtt ) or ( methode vi bavel / gtt ))) or ( methode 2i bavel / gtt ))) or ( methode v bavel / gtt )).
• Adding a wildcard symbol may retrieve word variants: (((((("methode van bavel / gtt") or ("methode vi bavel / gtt"))) or ("methode 2i bavel / gtt"))) or ("methode v bavel / gtt"))*.
