• Performing a fuzzy search may retrieve terms with similar spellings: tu cach tu nano xa hoi. hieu ve cam ((luc van) or (((luoc van) OR (luoc va)))) hanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach tu nano xa hoi. hieu ve cam ((luc van) OR (((luoc van) OR (luoc va)))) hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tu nano xa hoi. hieu ve cam ((luc van) or (((luoc van) OR (luoc va)))) hanh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu cach tu nano xa hoi. hieu ve cam ((luc van) or (((luoc van) OR (luoc va)))) hanh vai cua triet*.
