• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ((ty hang) OR (ly hang)) xa hoi. hieu van hau duc van anh ve cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ((ty hang) or (ly hang)) xa hoi. hieu van hau duc van anh ve cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ((ty hang) or (ly hang)) xa hoi. hieu van hau duc van anh ve cua tre*.
