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

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