• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh trung can ((((ban cong) OR (phan cong))) OR (van cong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh trung can ((((ban cong) OR (phan cong))) or (van cong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung can ((((ban cong) OR (phan cong))) or (van cong)) dan than cau*.
