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