• Performing a fuzzy search may retrieve terms with similar spellings: tu bai ky nang ((x hoi) OR (x ho)). ((hieu ve) or (hieu van)) cac xuc van hanh dinh cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu bai ky nang ((x hoi) OR (x ho)). ((hieu ve) OR (hieu van)) cac xuc van hanh dinh cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ky nang ((x hoi) OR (x ho)). ((hieu ve) or (hieu van)) cac xuc van hanh dinh cua tre*".
