• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((thanh truong) OR (((thanh trung) OR (thanh tung)))) cua dang trong tinh van dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((thanh truong) or (((thanh trung) OR (thanh tung)))) cua dang trong tinh van dau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((thanh truong) or (((thanh trung) OR (thanh tung)))) cua dang trong tinh van dau*.
