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