• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ky nang ma hoi. hieu ve ((cam tuc) or (cam tu)) va hanh vi ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky nang ma hoi. hieu ve ((cam tuc) OR (cam tu)) va hanh vi ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky nang ma hoi. hieu ve ((cam tuc) or (cam tu)) va hanh vi ((cua viet) OR (ca viet))".
