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