• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (hoc thieu)) sach - thanh ((vuong thuat) OR (thuong thuat)) hung cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sach - thanh ((vuong thuat) OR (thuong thuat)) hung cong dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - thanh ((vuong thuat) OR (thuong thuat)) hung cong dan toan cau*".
