• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((songs can) OR (bonds can)) cost sharing a ((long du) OR (long ago)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((songs can) OR (bonds can)) cost sharing a ((long du) or (long ago)) ;*".
