• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (((te sach) OR (toc sach)))) ky nang xa hoi. hieu tu cham tuc va danh van ca viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (((te sach) OR (toc sach)))) ky nang xa hoi. hieu tu cham tuc va danh van ca viet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (((te sach) OR (toc sach)))) ky nang xa hoi. hieu tu cham tuc va danh van ca viet*.
