ho chieu » theo chieu, hoc thieu, doi chieu
tong van » trong van, thong van, tang van

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo tieu)) xanh - ((hanh tang) OR (hanh trang)) cua han tong van phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - ((hanh tang) OR (hanh trang)) cua han tong van phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) xanh - ((hanh tang) OR (hanh trang)) cua han tong van phan cau*.
