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