• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ly hang xa hoi. thien van cham ((luc va) OR (tuc va)) doanh vang cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ly hang xa hoi. thien van cham ((luc va) or (tuc va)) doanh vang cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ly hang xa hoi. thien van cham ((luc va) or (tuc va)) doanh vang cua tre*.
