Perhaps you should try some spelling variations:
"critic" » "critics", "critica"
"criticas" » "criticsas", "criticaas"
"criticaas" » "criticsaas", "criticaaas"
"critical" » "criticsal", "criticaal"
"criticaal" » "criticsaal", "criticaaal"

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