hoc chieu » hoc thieu, ho chieu, hoc hien
vap nhung » va nhung, ve nhung, voi nhung
dap nhung » va nhung, dap ung, cam nhung
manh toan » thanh toan, anh tuan, tinh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - thanh trung ((vap nhung) OR (dap nhung)) cong ((san toan) OR (manh toan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh trung ((vap nhung) or (dap nhung)) cong ((san toan) OR (manh toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh trung ((vap nhung) or (dap nhung)) cong ((san toan) OR (manh toan)) ban*.
