• Performing a fuzzy search may retrieve terms with similar spellings: thu sach thi lang xa hoi. hieu ve nham thuc va hanh ((((vai cua) OR (hai cua))) or (lai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thi lang xa hoi. hieu ve nham thuc va hanh ((((vai cua) OR (hai cua))) OR (lai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thi lang xa hoi. hieu ve nham thuc va hanh ((((vai cua) OR (hai cua))) or (lai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: thu sach thi lang xa hoi. hieu ve nham thuc va hanh ((((vai cua) OR (hai cua))) or (lai cua)) triet*.
