Perhaps you should try some spelling variations:
"critica" » "critical", "criticala"
"criticas" » "criticals", "critical", "criticism", "critico", "criticalas"
"critics" » "criticism", "critical", "criticals"
"critic" » "critical"

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