• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty nang x hoi. lieu va cham soc van anh vi ((cau theo) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ty nang x hoi. lieu va cham soc van anh vi ((cau theo) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ty nang x hoi. lieu va cham soc van anh vi ((cau theo) or (cua triet))*.
