dong manh » duong manh, dong anh, dang manh
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
tang cua » mang cua, hang cua, tang luan
toan cau » toan cao, toan ban, toan tap

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