• If you are trying to use Boolean operators, they must be ALL CAPS: lang yanling ((yang xi) OR (((((yang lin) OR (yang li))) OR (yang jin)))) lee joan smith tom hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((yang xi) or (((((yang lin) OR (yang li))) or (yang jin)))) lee joan smith tom hui ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((yang xi) or (((((yang lin) OR (yang li))) or (yang jin)))) lee joan smith tom hui ;*.
