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