• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. ((hieu ve) OR (hieu van)) cam tuc van anh ((vai cua) or (lai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. ((hieu ve) OR (hieu van)) cam tuc van anh ((vai cua) OR (lai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. ((hieu ve) OR (hieu van)) cam tuc van anh ((vai cua) or (lai cua)) triet*".
