• If you are trying to use Boolean operators, they must be ALL CAPS: dong yang yala ((((hua credit) OR (dual credit))) OR (a credit)) trading cost computing shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yala ((((hua credit) OR (dual credit))) or (a credit)) trading cost computing shu ;*".
