• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (thien thanh)) - ((hanh tinh) OR (nhan sinh)) cua nhung hong van toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) OR (thien thanh)) - ((hanh tinh) or (nhan sinh)) cua nhung hong van toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) OR (thien thanh)) - ((hanh tinh) or (nhan sinh)) cua nhung hong van toan cao*.
