Perhaps you should try some spelling variations:
"critica" » "critics"
"criticaal" » "criticsal", "criticial", "criticcal", "critically"
"critical" » "criticsl"
"criticaaal" » "criticsaal", "criticial", "criticavel", "criticcal"

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