• Performing a fuzzy search may retrieve terms with similar spellings: "(othmar OR othman) ((((spains" OR spain") OR (pans" OR spans")) OR scans") OR span")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(othmar OR othman) ((((spains\" OR spain\") OR (pans\" OR spans\")) OR scans\") OR span\")".
• Removing quotes may allow a broader search: (othmar OR othman) ((((spains OR spain ) OR (pans OR spans )) OR scans ) OR span ).
• Adding a wildcard symbol may retrieve word variants: "(othmar OR othman) ((((spains" OR spain") OR (pans" OR spans")) OR scans") OR span")*.
