Perhaps you should try some spelling variations:
"critic" » "critica"
"critical" » "criticaal"
"criticaal" » "criticaaal"
"critics" » "criticas"
"criticas" » "criticaas"

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