Perhaps you should try some spelling variations:
polen » poolen, polyen, pollen, popen, posen, polyn
pol » pool, poly, poll
pole » poole, polye, polle, pope, pose, poly
pollees » poollees, polylees, polllees, polleres, polluees, pollens
polllees » poolllees, polyllees, pollllees, polluees, pollens, polleres
prallelen » parallellen, paralleler, paralleled
parallelen » parallele, parallel

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: (((polen OR (pol OR pole)) OR ((prallelen OR parallelen) OR post)) OR (pollees OR polllees)).
• Adding a wildcard symbol may retrieve word variants: (((polen or (pol or pole)) or ((prallelen or parallelen) or post)) or (pollees or polllees))*.
