manh trung » thanh trung, manh hung, sinh trung
hoc chieu » hoc thieu, ho chieu, hoc hien
manh tung » manh hung, thanh tung
cong nong » cong dong, cong cong, cong trong
nong tan » cong tan, nong dan, nong san
toan cao » toan ban
toan tap » toan ban

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - ((manh trung) OR (manh tung)) cua cong nong tan ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((manh trung) or (manh tung)) cua cong nong tan ((toan cao) or (toan tap))*.
