Perhaps you should try some spelling variations:
"critics" » "criticism"
"criticala" » "critically", "critica", "criticas"
"criticaland" » "criticallynd", "criticand", "criticasnd", "criticavano", "criticismand", "practicaland"
"criticalto" » "criticality", "criticalfor", "critically"

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