Perhaps you should try some spelling variations:
"polemicos" » "polemico", "politicos", "polemical"
"polemicss" » "polemicists", "polemicises", "polemicist", "polemicals"
"polemicas" » "polemical", "polemica", "politicas"
"polemics" » "polemical"

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 ("polemicss" OR ("polemicas" OR "polemics"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"polemicos\" or (\"polemicss\" or (\"polemicas\" OR \"polemics\")))".
• Removing quotes may allow a broader search: ( polemicos or ( polemicss or ( polemicas OR polemics ))).
• Adding a wildcard symbol may retrieve word variants: ("polemicos" or ("polemicss" or ("polemicas" OR "polemics")))*.
