Perhaps you should try some spelling variations:
"polemicas" » "polemical", "polemics", "polemica"
"polemicized" » "politicized", "polemicises", "polemicizing"
"polemicist" » "polemicists", "polemics", "polemicos"
"polemicised" » "polemicises", "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 (("polemicized" OR "polemicist") OR "polemicised")).
• Removing quotes may allow a broader search: ( polemicas or (( polemicized or polemicist ) or polemicised )).
• Adding a wildcard symbol may retrieve word variants: ("polemicas" or (("polemicized" or "polemicist") or "polemicised"))*.
