• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((yang yu) OR (yang yue)) ((cheng ying) OR (cheng bing)) jin wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yang yu) or (yang yue)) ((cheng ying) OR (cheng bing)) jin wong sau ;".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yang yu) or (yang yue)) ((cheng ying) OR (cheng bing)) jin wong sau ;*.
