• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tay ((dang xay) OR (van xay)) hoi. hieu ve cam ((xuc va) OR (duc va)) manh huong cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tay ((dang xay) OR (van xay)) hoi. hieu ve cam ((xuc va) or (duc va)) manh huong cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach tay ((dang xay) OR (van xay)) hoi. hieu ve cam ((xuc va) or (duc va)) manh huong cua tre*.
