• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu nang tao hoi. hieu su cham ((loc va) or (hoc va)) hanh lam ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu nang tao hoi. hieu su cham ((loc va) OR (hoc va)) hanh lam ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu nang tao hoi. hieu su cham ((loc va) or (hoc va)) hanh lam ((cua tre) OR (cua triet))*".
