• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((thu lang) OR (thu hang)) xa hoi. thi van cam ((xuc va) OR (thuc dan)) hanh hai cuu tre".
• Adding a wildcard symbol may retrieve word variants: su sach ((thu lang) OR (thu hang)) xa hoi. thi van cam ((xuc va) OR (thuc dan)) hanh hai cuu tre*.
