• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (((((dong yang) OR (wang yang))) OR (dong ping)))) ya your best data mun young yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (((((dong yang) OR (wang yang))) or (dong ping)))) ya your best data mun young yu ;".
