Perhaps you should try some spelling variations:
"critic" » "critica"
"critical" » "criticaal"
"criticaal" » "criticaaal"
"critics" » "criticas"
"criticas" » "criticaas"

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