• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh toan ((van nhung) OR (va nhung)) cong tan ((than cua) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh toan ((van nhung) OR (va nhung)) cong tan ((than cua) or (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh toan ((van nhung) OR (va nhung)) cong tan ((than cua) or (thanh lap))*.
