• Performing a fuzzy search may retrieve terms with similar spellings: "((weber von) OR (werkes von)) siemens (((rgginge" OR (ingeee" OR gingoee")) OR ringo") OR ing")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((weber von) OR (werkes von)) siemens (((rgginge\" OR (ingeee\" OR gingoee\")) OR ringo\") OR ing\")".
• Removing quotes may allow a broader search: ((weber von) OR (werkes von)) siemens (((rgginge OR (ingeee OR gingoee )) OR ringo ) OR ing ).
• Adding a wildcard symbol may retrieve word variants: "((weber von) OR (werkes von)) siemens (((rgginge" OR (ingeee" OR gingoee")) OR ringo") OR ing")*.
