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