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

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 ( (polemicises OR polemicist) OR polemicised ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "( polemicas or ( (polemicises OR polemicist) or polemicised ))*".
