• Performing a fuzzy search may retrieve terms with similar spellings: tu san ((ky tang) or (ky dang)) xa hoi. hieu vien bach xuc van anh cam ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky tang) OR (ky dang)) xa hoi. hieu vien bach xuc van anh cam ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky tang) or (ky dang)) xa hoi. hieu vien bach xuc van anh cam ((cua triet) OR (cua viet))*".
