• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tinh - manh truong cua ((nhung dung) OR (nhung phuong)) ((dan toan) OR (manh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - manh truong cua ((nhung dung) or (nhung phuong)) ((dan toan) or (manh toan)) cao*.
