Perhaps you should try some spelling variations:
"critic" » "critics", "critical"
"critica" » "criticsa", "criticala"
"criticsa" » "criticssa", "criticalsa"
"criticals" » "criticsals", "criticalals"
"criticsals" » "criticssals", "criticalsals"

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