• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky danh ((ma hoi) OR (mai hoi)). hieu ((ve cac) OR (va cac)) duc va hang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky danh ((ma hoi) OR (mai hoi)). hieu ((ve cac) or (va cac)) duc va hang tai cua tre".
