Perhaps you should try some spelling variations:
"critical" » "criticsl"
"critica" » "critics"
"criticala" » "criticsla", "criticaland", "critically", "criticalto"
"criticsla" » "critics", "criticsim", "criticsm"
"criticita" » "criticism", "criticize", "criticsta", "criticta", "criticota"
"critici" » "critics", "critic", "critico"

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