• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi anh - ((hanh tranh) OR (hanh trinh)) va ((nhung cuong) OR (hung cuong)) tap quan cao~.
• Adding a wildcard symbol may retrieve word variants: doi chi anh - ((hanh tranh) or (hanh trinh)) va ((nhung cuong) or (hung cuong)) tap quan cao*.
