Perhaps you should try some spelling variations:
pol » pool, poly, pole
polyp » poolyp, polyyp, poleyp
polya » poolya, polyya, poleya
polyeeis » poolyeeis, polyyeeis, poleyeeis, polyeders, polyenes
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: ((pol OR (polyp OR polya)) OR (polyeeis OR holes)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((pol or (polyp OR polya)) or (polyeeis or holes))".
• Adding a wildcard symbol may retrieve word variants: ((pol or (polyp OR polya)) or (polyeeis or holes))*.
