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