Perhaps you should try some spelling variations:
"resister" » "resisted", "resistors", "resistenz"
"restriktiver" » "restriktive", "restriktiven", "restriktionen"
"restrictive" » "destructive", "restriction", "restrictions"
"resistor" » "resistors", "resisted"

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: (("resister" OR ("restriktiver" OR "restrictive")) OR ("resistor" OR "resist")).
• Removing quotes may allow a broader search: (( resister or ( restriktiver or restrictive )) or ( resistor or resist )).
• Adding a wildcard symbol may retrieve word variants: (("resister" or ("restriktiver" or "restrictive")) or ("resistor" or "resist"))*.
