• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yuan chia tan ((yong lin) OR (song bing)) ((((zong hai) OR (long han))) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yuan chia tan ((yong lin) or (song bing)) ((((zong hai) OR (long han))) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yuan chia tan ((yong lin) or (song bing)) ((((zong hai) OR (long han))) or (hong hai)) ;*.
