• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (lieu tinh)) - ((thanh hang) OR (tran trong)) cua van cong tan doan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (lieu tinh)) - ((thanh hang) or (tran trong)) cua van cong tan doan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (lieu tinh)) - ((thanh hang) or (tran trong)) cua van cong tan doan tap*.
