• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ve gap nguoi dao hanh ((de cua) OR (((dieu cua) OR (dieu tra)))) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ve gap nguoi dao hanh ((de cua) or (((dieu cua) OR (dieu tra)))) tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ve gap nguoi dao hanh ((de cua) or (((dieu cua) OR (dieu tra)))) tre*.
