• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu sach) OR (chiet tach)) - thanh trung cua hang ((nong san) OR (nong dan)) thanh hai*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu sach) or (chiet tach)) - thanh trung cua hang ((nong san) OR (nong dan)) thanh hai*".
