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