• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (hoc thieu)) sach - thanh trung tuan nhung ((cong vang) OR (cong quang)) tan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (hoc thieu)) sach - thanh trung tuan nhung ((cong vang) OR (cong quang)) tan cau~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (hoc thieu)) sach - thanh trung tuan nhung ((cong vang) OR (cong quang)) tan cau*.
