• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yang yang)) ka hua irene ((yang lin) OR (yang jin)) hong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang yang)) ka hua irene ((yang lin) OR (yang jin)) hong hai ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang yang)) ka hua irene ((yang lin) OR (yang jin)) hong hai ;*.
