• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((song 2) OR (long 2)) cost sharing a ((((long seo) OR (long des))) OR (long ago)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((song 2) OR (long 2)) cost sharing a ((((long seo) or (long des))) or (long ago)) ;*".
