Perhaps you should try some spelling variations:
"critic" » "critics", "critica"
"critical" » "criticsal", "criticaal"
"criticaal" » "criticsaal", "criticaaal"
"criticsal" » "criticssal", "criticasal"
"criticsa" » "criticssa", "criticasa"

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