• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - anh mang cua cong ((nong anh) OR (((dong anh) OR (hong anh)))) tuan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - anh mang cua cong ((nong anh) or (((dong anh) OR (hong anh)))) tuan tap~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - anh mang cua cong ((nong anh) or (((dong anh) OR (hong anh)))) tuan tap*.
