• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sach - ((hanh trung) OR (manh trung)) cap nhung cong vinh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) sach - ((hanh trung) OR (manh trung)) cap nhung cong vinh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) sach - ((hanh trung) OR (manh trung)) cap nhung cong vinh toan cao*.
