• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ly nang x hoi. hieu ve ((chat luc) OR (nhan luc)) va danh van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ly nang x hoi. hieu ve ((chat luc) OR (nhan luc)) va danh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ly nang x hoi. hieu ve ((chat luc) OR (nhan luc)) va danh van cua tre*".
