• Performing a fuzzy search may retrieve terms with similar spellings: ((wang qian) or (wang li)) yi a centre ((((model erm3) OR (model elmm))) or (model ecm)) und sala ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang qian) OR (wang li)) yi a centre ((((model erm3) OR (model elmm))) OR (model ecm)) und sala ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang qian) or (wang li)) yi a centre ((((model erm3) OR (model elmm))) or (model ecm)) und sala ;".
• Adding a wildcard symbol may retrieve word variants: ((wang qian) or (wang li)) yi a centre ((((model erm3) OR (model elmm))) or (model ecm)) und sala ;*.
