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