• If you are trying to use Boolean operators, they must be ALL CAPS: doi khia canh - ((((hanh truong) OR (hanh trong))) OR (dinh thuong)) ca thong cong tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: doi khia canh - ((((hanh truong) or (hanh trong))) or (dinh thuong)) ca thong cong tan toan cao*.
