• Performing a fuzzy search may retrieve terms with similar spellings: (( bao bi kip ren luyen ky sang ma. Đo tuoi 7-15 ) or ( bo bi kin ((tre tuyen) OR (truc tuyen)) ky sang ma. Đo tuoi 7-15 ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( bao bi kip ren luyen ky sang ma. Đo tuoi 7-15 ) OR ( bo bi kin ((tre tuyen) OR (truc tuyen)) ky sang ma. Đo tuoi 7-15 )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bao bi kip ren luyen ky sang ma. Đo tuoi 7-15 ) or ( bo bi kin ((tre tuyen) OR (truc tuyen)) ky sang ma. Đo tuoi 7-15 ))".
