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