• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) thi hanh xu hoi. hieu ve cam luc va hanh ((thai cua) OR (tri cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) thi hanh xu hoi. hieu ve cam luc va hanh ((thai cua) OR (tri cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) thi hanh xu hoi. hieu ve cam luc va hanh ((thai cua) OR (tri cua)) triet".
