• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang van hoi. ((hieu ve) OR (hieu va)) cam duc tan hanh ((ve cau) OR (va cau)) treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang van hoi. ((hieu ve) or (hieu va)) cam duc tan hanh ((ve cau) OR (va cau)) treo*".
