• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang ma hoi. ((lieu ha) OR (lieu va)) nam thuc xay hanh tai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ma hoi. ((lieu ha) OR (lieu va)) nam thuc xay hanh tai ((cuu tre) or (cau treo))*".
