Perhaps you should try some spelling variations:
poleznyi » poleznyj, poleznykh, polanyi, pooleznyi, polyeznyi, poleeznyi
pol » pool, poly, pole
polyele » poolyele, polyyele, poleyele, polyeder, polyenes, polyedre
polyene » poolyene, polyyene, poleyene, polyenes, polyeder
polis » poolis, polyis, poleis, polish, poles, polls
pooley » pooled, cooley, tooley, pooledy, poley, poolsy
poole » pooled, pole, pools

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: (((poleznyi OR pol) OR ((polyele OR polyene) OR pope)) OR (polis OR (pooley OR poole))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((poleznyi or pol) or ((polyele OR polyene) or pope)) or (polis or (pooley or poole)))".
• Adding a wildcard symbol may retrieve word variants: (((poleznyi or pol) or ((polyele OR polyene) or pope)) or (polis or (pooley or poole)))*.
