• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (hieu lang)) - ((hanh trung) OR (manh trung)) tran thong cong san thanh chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (hieu lang)) - ((hanh trung) or (manh trung)) tran thong cong san thanh chau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) OR (hieu lang)) - ((hanh trung) or (manh trung)) tran thong cong san thanh chau*.
