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