• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu va lam truoc va tinh vi ((cua triet) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky nang xa hoi. hieu va lam truoc va tinh vi ((cua triet) or (cua tu))".
