• If you are trying to use Boolean operators, they must be ALL CAPS: cho ho manh - ((canh tranh) OR (hanh trinh)) cua thuong cong dan ((than cao) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ho manh - ((canh tranh) or (hanh trinh)) cua thuong cong dan ((than cao) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: cho ho manh - ((canh tranh) or (hanh trinh)) cua thuong cong dan ((than cao) OR (than cap))*.
