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