• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu tang van hoi. hieu ((((va cam) OR (va cac))) OR (va cao)) thuc vat thanh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu tang van hoi. hieu ((((va cam) OR (va cac))) or (va cao)) thuc vat thanh dai cua te*".
