Perhaps you should try some spelling variations:
"methode vi baked / gtt" » "methoden vi baked / gtt", "methode 2 baked / gtt", "methode 1 baked / gtt", "methode 2i baked / gtt", "methode 4i baked / gtt", "methode 1i baked / gtt", "methode vi based / gtt", "methode _ baked / gtt", "methode 15 baked / gtt"
"methode von bavel / gtt" » "methode van bavel / gtt", "methode von babel / gtt", "methode von gavel / gtt", "methode 2on bavel / gtt", "methode 4on bavel / gtt", "methode 1on bavel / gtt"
"methode 3 bavel / gtt" » "methode 2 bavel / gtt", "methode 3 basel / gtt"
"methode v bavel / gtt" » "methode 2 bavel / gtt", "methode 4 bavel / gtt", "methode 1 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 von bavel / gtt") OR ((("methode 3 bavel / gtt") OR ("methode vi baked / gtt"))))) OR ("methode v bavel / gtt")).
• Removing quotes may allow a broader search: (((( methode von bavel / gtt ) or ((( methode 3 bavel / gtt ) or ( methode vi baked / gtt ))))) or ( methode v bavel / gtt )).
• Adding a wildcard symbol may retrieve word variants: (((("methode von bavel / gtt") or ((("methode 3 bavel / gtt") or ("methode vi baked / gtt"))))) or ("methode v bavel / gtt"))*.
