• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"1989 iaaf world op\") OR (((((\"1989 imf world op\") OR (((\"1989 imf wereld op\") OR (\"1989 imf wereld en\"))))) OR (\"1989 imf world we\"))))) OR (\"1989 iaaf wordt er\"))~".
• Removing quotes may allow a broader search: (((( 1989 iaaf world op ) OR ((((( 1989 imf world op ) OR ((( 1989 imf wereld op ) OR ( 1989 imf wereld en ))))) OR ( 1989 imf world we ))))) OR ( 1989 iaaf wordt er ))~.
• Adding a wildcard symbol may retrieve word variants: (((("1989 iaaf world op") OR ((((("1989 imf world op") OR ((("1989 imf wereld op") OR ("1989 imf wereld en"))))) OR ("1989 imf world we"))))) OR ("1989 iaaf wordt er"))*.
