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