• Performing a fuzzy search may retrieve terms with similar spellings: su sai ky nang xa hoi. ((hieu van) OR (hieu va)) hai truc ((ban hanh) or (van anh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang xa hoi. ((hieu van) OR (hieu va)) hai truc ((ban hanh) OR (van anh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang xa hoi. ((hieu van) OR (hieu va)) hai truc ((ban hanh) or (van anh)) vi cua tre*".
