• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yang hui) OR (yang jui)) ((li sang) OR (le sang)) minh congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang hui) OR (yang jui)) ((li sang) or (le sang)) minh congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang hui) OR (yang jui)) ((li sang) or (le sang)) minh congo shu ;*.
