chieu xanh » chieu sach, chieu sang, chieu tinh
thien anh » thien danh, tien anh, thien thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (thien anh)) - hanh trang cua thong huong dan ((han tap) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (thien anh)) - hanh trang cua thong huong dan ((han tap) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (thien anh)) - hanh trang cua thong huong dan ((han tap) OR (toan tap))*.
