• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ((v nang) OR (van nang)) ma hoi. lieu va cam luc va tinh vi ((cua tre) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ((v nang) OR (van nang)) ma hoi. lieu va cam luc va tinh vi ((cua tre) or (cua tuc))".
