• Performing a fuzzy search may retrieve terms with similar spellings: (( tu cach cha me ((giai bon) OR (giai han)) thong tin ) or ( te sach che me gioi bon thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach cha me ((giai bon) OR (giai han)) thong tin ) OR ( te sach che me gioi bon thong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cach cha me ((giai bon) OR (giai han)) thong tin ) or ( te sach che me gioi bon thong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( tu cach cha me ((giai bon) OR (giai han)) thong tin ) or ( te sach che me gioi bon thong tin ))*.
