• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (cach tu)) lang xa hoi. hieu va lam luc va nang via ((cua viet) OR (hoa viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) or (cach tu)) lang xa hoi. hieu va lam luc va nang via ((cua viet) OR (hoa viet))".
• Adding a wildcard symbol may retrieve word variants: te ((sach tu) or (cach tu)) lang xa hoi. hieu va lam luc va nang via ((cua viet) OR (hoa viet))*.
