• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh hang cua ((dang phuong) OR (dung phuong)) ((van toan) OR (ban than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh hang cua ((dang phuong) OR (dung phuong)) ((van toan) or (ban than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh hang cua ((dang phuong) OR (dung phuong)) ((van toan) or (ban than)) cau*.
