• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu bai)) ky nang co hoc. thien van ((cham soc) OR (chao xu)) va thanh lap cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu bai)) ky nang co hoc. thien van ((cham soc) or (chao xu)) va thanh lap cuu tre".
