• If you are trying to use Boolean operators, they must be ALL CAPS: ((( crac OR ((grade OR gnave) OR have)) cyclist ) OR (( traces OR ( treces OR traes)) cyclist ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((( crac OR ((grade OR gnave) OR have)) cyclist ) OR (( traces OR ( treces OR traes)) cyclist ))~".
• Adding a wildcard symbol may retrieve word variants: ((( crac OR ((grade OR gnave) OR have)) cyclist ) OR (( traces OR ( treces OR traes)) cyclist ))*.
