• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sach - ((hanh hang) OR (hang hang)) va dung trong van chat va*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sach - ((hanh hang) or (hang hang)) va dung trong van chat va*".
