• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ((y nang) OR (ly hang)) ma hoi. hieu van cau xuc va dinh dai cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ((y nang) or (ly hang)) ma hoi. hieu van cau xuc va dinh dai cua viet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) ((y nang) or (ly hang)) ma hoi. hieu van cau xuc va dinh dai cua viet*.
