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