• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky lang) OR (ky tang)) xa hoi. ((hieu van) or (lieu va)) bac xuc va thanh than va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky lang) OR (ky tang)) xa hoi. ((hieu van) OR (lieu va)) bac xuc va thanh than va triet.
