• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu hang ((x hoi) or (x ho)). hieu va cac xuc van thanh di ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu hang ((x hoi) OR (x ho)). hieu va cac xuc van thanh di ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu hang ((x hoi) or (x ho)). hieu va cac xuc van thanh di ((cua triet) OR (cua viet))*".
