• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty lang) OR (ty hang)) ha hoi. lieu va tham ((duc van) OR (duc tan)) hanh vai cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty lang) OR (ty hang)) ha hoi. lieu va tham ((duc van) or (duc tan)) hanh vai cua su".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty lang) OR (ty hang)) ha hoi. lieu va tham ((duc van) or (duc tan)) hanh vai cua su*.
