Perhaps you should try some spelling variations:
"methode van bavel / gtt" » "methode von bavel / gtt", "methode vom bavel / gtt", "methode viii bavel / gtt", "methode 3an bavel / gtt", "methode 4an bavel / gtt", "methode 1an bavel / gtt"
"methoden vi bavel / gtt" » "methoden v bavel / gtt", "methoden von bavel / gtt", "methoden 1 bavel / gtt", "methoden vi based / gtt", "methoden vi baked / gtt", "methoden vi bases / gtt"
"methode vii bavel / gtt" » "methoden vii bavel / gtt", "methods vii bavel / gtt", "method vii bavel / gtt", "methode voni bavel / gtt", "methode 3i bavel / gtt", "methode 1i bavel / gtt", "methode vii bases / gtt", "methode 3ii bavel / gtt", "methode 4ii bavel / gtt", "methode 1ii bavel / gtt"
"methode vi bavel / gtt" » "methode von bavel / gtt", "methode 3 bavel / gtt", "methode 1 bavel / gtt", "methode 3i bavel / gtt", "methode 4i bavel / gtt", "methode 1i bavel / gtt", "methode vi based / gtt", "methode vi baked / gtt", "methode vi bases / gtt"
"methode 3i bavel / gtt" » "methode 3 bavel / gtt", "methode 31 bavel / gtt", "methode 32 bavel / gtt"
"methode v bavel / gtt" » "methode 3 bavel / gtt", "methode 4 bavel / gtt", "methode 1 bavel / gtt", "methode v bavula / gtt"
"methode 2 bavel / gtt" » "methode 2 babel / 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 van bavel / gtt") OR ((((("methode vi bavel / gtt") OR ("methoden vi bavel / gtt"))) OR ("methode 3i bavel / gtt"))))) OR ("methode vii bavel / gtt"))) OR ((("methode v bavel / gtt") OR ("methode 2 bavel / gtt")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"methode van bavel / gtt\") or (((((\"methode vi bavel / gtt\") OR (\"methoden vi bavel / gtt\"))) or (\"methode 3i bavel / gtt\"))))) or (\"methode vii bavel / gtt\"))) or (((\"methode v bavel / gtt\") or (\"methode 2 bavel / gtt\"))))".
• Removing quotes may allow a broader search: (((((( methode van bavel / gtt ) or ((((( methode vi bavel / gtt ) OR ( methoden vi bavel / gtt ))) or ( methode 3i bavel / gtt ))))) or ( methode vii bavel / gtt ))) or ((( methode v bavel / gtt ) or ( methode 2 bavel / gtt )))).
• Adding a wildcard symbol may retrieve word variants: (((((("methode van bavel / gtt") or ((((("methode vi bavel / gtt") OR ("methoden vi bavel / gtt"))) or ("methode 3i bavel / gtt"))))) or ("methode vii bavel / gtt"))) or ((("methode v bavel / gtt") or ("methode 2 bavel / gtt"))))*.
