• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang co) OR (nang doc)) hoi. thien va cham ((xac va) OR (duc va)) thanh lap phu tho*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang co) OR (nang doc)) hoi. thien va cham ((xac va) or (duc va)) thanh lap phu tho*".
