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

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