Perhaps you should try some spelling variations:
"critica" » "critical"
"criticala" » "criticalla", "critical", "criticaland", "critically"
"critics" » "criticism", "critical"
"criticial" » "critical", "criticism", "criticize"

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