ho chieu » hoc thieu, doi chieu, mot chieu
tinh cua » trinh cua, sinh cua, tinh chat

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