Perhaps you should try some spelling variations:
"resistir" » "resister", "resisting", "resistors"
"resistive" » "assistive", "resisting"
"resistiver" » "assistiver", "resistingr", "resister", "restriktiver"
"resistor" » "resistors", "resist", "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: ((("resistir" OR "resistive") OR "resistiver") OR "resistor").
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"resistir\" OR \"resistive\") or \"resistiver\") or \"resistor\")".
• Removing quotes may allow a broader search: ((( resistir OR resistive ) or resistiver ) or resistor ).
• Adding a wildcard symbol may retrieve word variants: ((("resistir" OR "resistive") or "resistiver") or "resistor")*.
