• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach y lang xa hoi. thien van cac ((xuc va) OR (tuc va)) hanh ((lai cua) OR (lai chau)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach y lang xa hoi. thien van cac ((xuc va) or (tuc va)) hanh ((lai cua) OR (lai chau)) tu".
• Adding a wildcard symbol may retrieve word variants: vu khach y lang xa hoi. thien van cac ((xuc va) or (tuc va)) hanh ((lai cua) OR (lai chau)) tu*.
