• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - thanh ((huong dai) OR (duong dai)) ((nhung duong) OR (nhung huong)) thanh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - thanh ((huong dai) OR (duong dai)) ((nhung duong) or (nhung huong)) thanh toan tap".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - thanh ((huong dai) OR (duong dai)) ((nhung duong) or (nhung huong)) thanh toan tap*.
