• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chua xang)) - thanh ((hang can) OR (hang ban)) dang huong dai cua cay.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chua xang)) - thanh ((hang can) or (hang ban)) dang huong dai cua cay".
