Perhaps you should try some spelling variations:
"methode vom bavel / gtt" » "methoden vom bavel / gtt", "methode vi bavel / gtt", "methode vii bavel / gtt", "methode vom braven / gtt", "methode van bavel / gtt", "methode vom bail / gtt", "methode viom bavel / gtt", "methode 2om bavel / gtt", "methode 4om bavel / gtt"
"methode von bavel / gtt" » "methode van bavel / gtt", "methode von babel / gtt", "methode von gavel / gtt", "methode vion bavel / gtt", "methode 2on bavel / gtt", "methode 4on bavel / gtt"
"methode 3 bavel / gtt" » "methode 2 bavel / gtt", "methode 3 basel / gtt"
"methode v bavel / gtt" » "methode vi bavel / gtt", "methode 2 bavel / gtt", "methode 4 bavel / gtt", "methode van bavel / gtt", "methode v bavula / gtt"

Try widening your search to All Fields.

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 vom bavel / gtt") OR ("methode von bavel / gtt"))) OR ("methode 3 bavel / gtt"))) OR ("methode v bavel / gtt")).
• Removing quotes may allow a broader search: (((((( methode vom bavel / gtt ) or ( methode von bavel / gtt ))) or ( methode 3 bavel / gtt ))) or ( methode v bavel / gtt )).
• Adding a wildcard symbol may retrieve word variants: (((((("methode vom bavel / gtt") or ("methode von bavel / gtt"))) or ("methode 3 bavel / gtt"))) or ("methode v bavel / gtt"))*.
