Perhaps you should try some spelling variations:
pol » pool, poly, poll
pole » poole, polye, polle, pope, pose, poly
polyion » poolyion, polyyion, pollyion, polyionic
polyanion » poolyanion, polyyanion, pollyanion, polyanions, polyanionic
poole » pooled, 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: ((pol OR (pole OR poole)) OR (polyion OR polyanion)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((pol or (pole or poole)) or (polyion OR polyanion))".
• Adding a wildcard symbol may retrieve word variants: ((pol or (pole or poole)) or (polyion OR polyanion))*.
