• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien thanh - ((((hanh trung) OR (manh tung))) OR (hanh trang)) nam nhung cong vang toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thien thanh - ((((hanh trung) or (manh tung))) or (hanh trang)) nam nhung cong vang toan cau*.
