Perhaps you should try some spelling variations:
"criticsm" » "criticism", "criticsim", "criticam", "criticismm"
"criticasa" » "criticism", "critica", "criticos", "criticaa", "criticisma"
"criticas" » "critica", "criticism", "critic"
"critics" » "criticism"

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