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