• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - thanh trung ha ((((hang cong) OR (bang cong))) OR (dang cong)) dan thuc bao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - thanh trung ha ((((hang cong) OR (bang cong))) or (dang cong)) dan thuc bao".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - thanh trung ha ((((hang cong) OR (bang cong))) or (dang cong)) dan thuc bao*.
