Perhaps you should try some spelling variations:
"critic" » "critics"
"critical" » "criticsal"
"critica" » "criticsa"
"criticals" » "criticsals"
"criticas" » "criticsas"

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