• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - hanh trung ((((cap thong) OR (phap thong))) OR (chap thuong)) cong tan toan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh trung ((((cap thong) or (phap thong))) or (chap thuong)) cong tan toan cau*.
