• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh trang) OR (hanh trinh)) cua thong cong ((dan chan) OR (dan ca)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh trang) OR (hanh trinh)) cua thong cong ((dan chan) or (dan ca)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh trang) OR (hanh trinh)) cua thong cong ((dan chan) or (dan ca)) tap*.
