• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ha me gioi ((con thong) OR (toan thong)) minh ) or ( tu sach ha le gioi con hong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ha me gioi ((con thong) OR (toan thong)) minh ) OR ( tu sach ha le gioi con hong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ha me gioi ((con thong) OR (toan thong)) minh ) or ( tu sach ha le gioi con hong minh ))".
