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

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