• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh tang) OR (hanh trang)) ((luan thong) OR (xuan phuong)) thong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh tang) OR (hanh trang)) ((luan thong) or (xuan phuong)) thong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh tang) OR (hanh trang)) ((luan thong) or (xuan phuong)) thong tan toan cau*.
