Perhaps you should try some spelling variations:
"resistir" » "resistor", "resisting", "resistive"
"resistiver" » "resistive", "restriktiver"
"resister" » "resistor", "resistenz", "resistent"
"resisted" » "assisted", "resist"

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: ((("resistir" OR "resistiver") OR "resister") OR ("resistors" OR "resisted")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"resistir\" OR \"resistiver\") or \"resister\") or (\"resistors\" or \"resisted\"))".
• Removing quotes may allow a broader search: ((( resistir OR resistiver ) or resister ) or ( resistors or resisted )).
• Adding a wildcard symbol may retrieve word variants: ((("resistir" OR "resistiver") or "resister") or ("resistors" or "resisted"))*.
