• If you are trying to use Boolean operators, they must be ALL CAPS: theo lieu tinh - hanh ((dong luan) OR (tang luan)) nhung cong ((van tai) OR (van tuan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo lieu tinh - hanh ((dong luan) or (tang luan)) nhung cong ((van tai) OR (van tuan)) cau*".
