• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ((ky sang) OR (ky nang)) ma hoi. hieu ve cac xuc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ((ky sang) or (ky nang)) ma hoi. hieu ve cac xuc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ((ky sang) or (ky nang)) ma hoi. hieu ve cac xuc va hanh vai cua tre*.
