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

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