• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (co sach)) ((ty nang) OR (ty hang)) xa hoi. hieu va cham luc va thanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (co sach)) ((ty nang) OR (ty hang)) xa hoi. hieu va cham luc va thanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (co sach)) ((ty nang) OR (ty hang)) xa hoi. hieu va cham luc va thanh vai cua tre*.
