• Performing a fuzzy search may retrieve terms with similar spellings: (( thu ((sach cha) OR (sach nha)) me gioi can hong minh ) or ( tu cac ca van giao nhan dong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu ((sach cha) OR (sach nha)) me gioi can hong minh ) OR ( tu cac ca van giao nhan dong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu ((sach cha) OR (sach nha)) me gioi can hong minh ) or ( tu cac ca van giao nhan dong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( thu ((sach cha) OR (sach nha)) me gioi can hong minh ) or ( tu cac ca van giao nhan dong minh ))*.
