• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky sang ((mai hoi) OR (lai hoi)). ((lieu va) OR (hieu va)) cam duc ban banh de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky sang ((mai hoi) OR (lai hoi)). ((lieu va) or (hieu va)) cam duc ban banh de cua tre".
