• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. hieu ((ve cham) OR (va cham)) xuc ((van anh) OR (tuan anh)) di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. hieu ((ve cham) OR (va cham)) xuc ((van anh) or (tuan anh)) di cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoi. hieu ((ve cham) OR (va cham)) xuc ((van anh) or (tuan anh)) di cua tre*.
