Perhaps you should try some spelling variations:
resistive » assistive, resisting
resistiver » assistiver, resistingr, resister, restriktiver
resistir » resistor, resister, resisting
assistiver » assistive, assister, assistierter

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: (resistive OR (resistir OR (resistiver OR assistiver))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(resistive or (resistir or (resistiver OR assistiver)))".
• Adding a wildcard symbol may retrieve word variants: (resistive or (resistir or (resistiver OR assistiver)))*.
