cua thong » cua thuong, cua khong, cua tong
thong van » trong van, thong va, thong quan
ho chieu » hoc thieu, doi chieu, mot chieu

van toan » van tuan, van tan, van thanh
toan cau » toan cao, toan ban, toan tap

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