• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang o hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh tay ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang o hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh tay ((cua tre) or (cuu tre))".
