• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. lieu va ((chat tuc) OR (chat huu)) xa hanh vi ((cau treo) OR (tu tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang xa hoi. lieu va ((chat tuc) OR (chat huu)) xa hanh vi ((cau treo) or (tu tren))".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang xa hoi. lieu va ((chat tuc) OR (chat huu)) xa hanh vi ((cau treo) or (tu tren))*.
