• Performing a fuzzy search may retrieve terms with similar spellings: (( thuat sach mkkxy thuat co khi ) or ( tu sach kxy ((thuat doi) OR (thuat di)) khi ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuat sach mkkxy thuat co khi ) OR ( tu sach kxy ((thuat doi) OR (thuat di)) khi ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thuat sach mkkxy thuat co khi ) or ( tu sach kxy ((thuat doi) OR (thuat di)) khi ))*".
