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