• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (chao chu)) xanh - hanh trang cua ((bang cong) OR (dang cong)) manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (chao chu)) xanh - hanh trang cua ((bang cong) or (dang cong)) manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (chao chu)) xanh - hanh trang cua ((bang cong) or (dang cong)) manh toan cau*.
