• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (doi chieu)) xanh - hanh trung ((cap nhung) OR (cam nhung)) cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (doi chieu)) xanh - hanh trung ((cap nhung) OR (cam nhung)) cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (doi chieu)) xanh - hanh trung ((cap nhung) OR (cam nhung)) cong tan toan cau*.
