Perhaps you should try some spelling variations:
"criticaal" » "critically", "criticavel", "critica"
"criticial" » "criticism", "critica", "criticize"
"criticcal" » "critica", "criticas", "acritical"
"criticals" » "criticas", "critically", "criticalto"

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