Perhaps you should try some spelling variations:
polemicas » polemical, polemics, polemica
polemicist » polemicists, polemicises, polemics
polemicised » polemicises, polemicized, polemicists
politicised » politicized

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: ( polemicas OR ( polemicist OR (polemicised OR politicised) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( polemicas or ( polemicist or (polemicised OR politicised) ))".
• Adding a wildcard symbol may retrieve word variants: ( polemicas or ( polemicist or (polemicised OR politicised) ))*.
