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