Perhaps you should try some spelling variations:
polyeis » polyenes, poolyeis, polyyeis, poleyeis
pol » pool, poly, pole
polyolen » poolyolen, polyyolen, poleyolen, polyole, polyosen, polyolefin
poole » pooled, pole
pooles » pooleds, poles, poodles, pooled, pooley
pools » tools
holes » roles, holds, hole

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: (((polyeis OR (pol OR poole)) OR (polyolen OR post)) OR ((pooles OR pools) OR holes)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((polyeis or (pol or poole)) or (polyolen or post)) or ((pooles OR pools) or holes))".
• Adding a wildcard symbol may retrieve word variants: (((polyeis or (pol or poole)) or (polyolen or post)) or ((pooles OR pools) or holes))*.
