• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu cac)) ((ky lang) OR (ky tang)) xa hoi. thien van cau loc va hanh sai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ((ky lang) OR (ky tang)) xa hoi. thien van cau loc va hanh sai cua te.
