• If you are trying to use Boolean operators, they must be ALL CAPS: ((((chao chieu) OR (theo chieu))) OR (chao chu)) tinh - manh trung cua dung cong tan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((chao chieu) OR (theo chieu))) or (chao chu)) tinh - manh trung cua dung cong tan than cao~".
• Adding a wildcard symbol may retrieve word variants: ((((chao chieu) OR (theo chieu))) or (chao chu)) tinh - manh trung cua dung cong tan than cao*.
