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