• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sach)) - thanh ((tinh va) OR (trinh vat)) hang long tinh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sach)) - thanh ((tinh va) or (trinh vat)) hang long tinh toan cau*".
