• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang xa hoi. hieu va cham ((xac va) OR (duc va)) thanh vi luu truc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ky nang xa hoi. hieu va cham ((xac va) or (duc va)) thanh vi luu truc".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) ky nang xa hoi. hieu va cham ((xac va) or (duc va)) thanh vi luu truc*.
