Perhaps you should try some spelling variations:
poleznyi » poleznyj, poleznykh, polanyi
pose » post
poses » posts, posed
poolsche » boolsche, polsche, pellsche, toolsche
toolsche » boolsche, bolsche, polsche
polees » polens, poleis, parolees
pools » tools

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: ((((poleyyi OR poleznyi) OR pose) OR ((poolsche OR toolsche) OR pope)) OR ((polees OR poses) OR pools)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((poleyyi OR poleznyi) or pose) or ((poolsche or toolsche) or pope)) or ((polees or poses) or pools))".
• Adding a wildcard symbol may retrieve word variants: ((((poleyyi OR poleznyi) or pose) or ((poolsche or toolsche) or pope)) or ((polees or poses) or pools))*.
