• Performing a fuzzy search may retrieve terms with similar spellings: ((wang qian) or (((wang li) OR (tang li)))) kyi a centre ((model eu) or (model ecm)) und sala ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang qian) OR (((wang li) OR (tang li)))) kyi a centre ((model eu) OR (model ecm)) und sala ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang qian) or (((wang li) OR (tang li)))) kyi a centre ((model eu) or (model ecm)) und sala ;".
• Adding a wildcard symbol may retrieve word variants: ((wang qian) or (((wang li) OR (tang li)))) kyi a centre ((model eu) or (model ecm)) und sala ;*.
