• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach thieu)) nang xa hoi. hieu vu ((cham xuc) OR (cam xuc)) va doanh van cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) or (sach thieu)) nang xa hoi. hieu vu ((cham xuc) OR (cam xuc)) va doanh van cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach thu) or (sach thieu)) nang xa hoi. hieu vu ((cham xuc) OR (cam xuc)) va doanh van cuu tre*.
