• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky lang) OR (ky tang)) xa hoi. lieu va dao xuc va ((hang thai) OR (hang hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky lang) OR (ky tang)) xa hoi. lieu va dao xuc va ((hang thai) or (hang hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky lang) OR (ky tang)) xa hoi. lieu va dao xuc va ((hang thai) or (hang hai)) cua tre*.
