• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang tai hoi. hieu ((ve cac) OR (va cac)) luc va ((danh hai) OR (dang hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang tai hoi. hieu ((ve cac) or (va cac)) luc va ((danh hai) OR (dang hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sai ky nang tai hoi. hieu ((ve cac) or (va cac)) luc va ((danh hai) OR (dang hai)) cua tre*.
