• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach che me gioi ((co dong) OR (o dong)) kinh ) or ( tu sach cha me giai han trong kinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che me gioi ((co dong) OR (o dong)) kinh ) OR ( tu sach cha me giai han trong kinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che me gioi ((co dong) OR (o dong)) kinh ) or ( tu sach cha me giai han trong kinh ))".
