• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - ((canh trang) OR (hanh trang)) va nhung hong hanh ((tuan cau) OR (tuan cu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - ((canh trang) OR (hanh trang)) va nhung hong hanh ((tuan cau) or (tuan cu))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - ((canh trang) OR (hanh trang)) va nhung hong hanh ((tuan cau) or (tuan cu))*.
