• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (tu sach)) ky nang ma hoi. ((hieu van) or (thien van)) lam tuc xa thanh ve cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ky nang ma hoi. ((hieu van) OR (thien van)) lam tuc xa thanh ve cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) ky nang ma hoi. ((hieu van) or (thien van)) lam tuc xa thanh ve cau treo*".
