• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doi chi)) sang - anh dung cua thong ((cong tap) OR (cuong tap)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (doi chi)) sang - anh dung cua thong ((cong tap) OR (cuong tap)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (doi chi)) sang - anh dung cua thong ((cong tap) OR (cuong tap)) toan cao*.
