• If you are trying to use Boolean operators, they must be ALL CAPS: wan you ((((qian yan) OR (qian yi))) OR (qiang niu)) reformen beim david ng hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan you ((((qian yan) OR (qian yi))) or (qiang niu)) reformen beim david ng hai ;*".
