• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (tu cach))) OR (te sach)) tri nang xa hoi. hieu toc cham duc van hanh de ve triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (tu cach))) or (te sach)) tri nang xa hoi. hieu toc cham duc van hanh de ve triet*".
