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