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