• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach y) or (sach ty)) tang ((ma hoi) OR (xa hoi)). hieu van bay dia ban thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sach ty)) tang ((ma hoi) OR (xa hoi)). hieu van bay dia ban thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach y) or (sach ty)) tang ((ma hoi) OR (xa hoi)). hieu van bay dia ban thanh vai cuu tre*".
