• If you are trying to use Boolean operators, they must be ALL CAPS: feng ((juan meng) OR (yuan ming)) hong cheng cheng hei ((hong ghi) OR (hong (tan OR than))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "feng ((juan meng) OR (yuan ming)) hong cheng cheng hei ((hong ghi) or (hong (tan or than))) ;~".
• Adding a wildcard symbol may retrieve word variants: feng ((juan meng) OR (yuan ming)) hong cheng cheng hei ((hong ghi) or (hong (tan or than))) ;*.
