• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chieu sach)) - hanh truong quan nhung cong tan ((than tap) OR (han tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) or (chieu sach)) - hanh truong quan nhung cong tan ((than tap) OR (han tap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (chieu sach)) - hanh truong quan nhung cong tan ((than tap) OR (han tap))*.
