Perhaps you should try some spelling variations:
"critical" » "criticsl"
"critica" » "critics"
"criticala" » "criticsla", "criticaland", "criticalto", "criticas"
"critically" » "criticslly"
"criticsa" » "critics", "criticsm", "criticism"
"criticssa" » "criticism", "critics", "criticas"

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: ("critical" OR (("critica" OR ("criticala" OR "critically")) OR ("criticsa" OR "criticssa"))).
• Removing quotes may allow a broader search: ( critical or (( critica or ( criticala or critically )) or ( criticsa or criticssa ))).
• Adding a wildcard symbol may retrieve word variants: ("critical" or (("critica" or ("criticala" or "critically")) or ("criticsa" or "criticssa")))*.
