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

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 ("polemicised" OR ("polemicized" OR "polemicises"))).
• Removing quotes may allow a broader search: ( polemicas or ( polemicised or ( polemicized or polemicises ))).
• Adding a wildcard symbol may retrieve word variants: ("polemicas" or ("polemicised" or ("polemicized" or "polemicises")))*.
