• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty hang) OR (ly hang)) xa hoi. hieu ve cham xuc va ((tinh thai) OR (tinh toan)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty hang) OR (ly hang)) xa hoi. hieu ve cham xuc va ((tinh thai) or (tinh toan)) cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty hang) OR (ly hang)) xa hoi. hieu ve cham xuc va ((tinh thai) or (tinh toan)) cau treo*.
