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