• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. hieu ve cac ((du ban) OR (duc ban)) thanh ((vai cua) or (thai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. hieu ve cac ((du ban) OR (duc ban)) thanh ((vai cua) OR (thai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. hieu ve cac ((du ban) OR (duc ban)) thanh ((vai cua) or (thai cua)) tre*".
