Perhaps you should try some spelling variations:
"methode viii bavel / gtt" » "methode iii bavel / gtt", "methods viii bavel / gtt", "methode vii bavel / gtt", "methode viii travel / gtt", "methode viii borel / gtt", "methode viiii bavel / gtt", "methode 2iii bavel / gtt", "methode 3iii bavel / gtt"
"methode 3an bavel / gtt" » "methode 3 bavel / gtt", "methode 3.1 bavel / gtt", "methode 3.4 bavel / gtt", "methode van bavel / gtt"
"methode 3ii bavel / gtt" » "methode 3 bavel / gtt", "methode 3.1 bavel / gtt", "methode 3.4 bavel / gtt"
"methode v bavel / gtt" » "methode vi bavel / gtt", "methode 2 bavel / gtt", "methode 3 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 3an bavel / gtt") OR ((("methode 3ii bavel / gtt") OR ("methode viii bavel / gtt"))))) OR ("methode v bavel / gtt")).
• Removing quotes may allow a broader search: (((( methode 3an bavel / gtt ) or ((( methode 3ii bavel / gtt ) or ( methode viii bavel / gtt ))))) or ( methode v bavel / gtt )).
• Adding a wildcard symbol may retrieve word variants: (((("methode 3an bavel / gtt") or ((("methode 3ii bavel / gtt") or ("methode viii bavel / gtt"))))) or ("methode v bavel / gtt"))*.
