• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((crac OR crc) OR cric) OR crack) OR cra) cyclist ) OR ( (trae OR prae) cyclist ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((crac OR crc) OR cric) OR crack) OR cra) cyclist ) OR ( (trae OR prae) cyclist ))~".
• Adding a wildcard symbol may retrieve word variants: (((( ((crac OR crc) OR cric) OR crack) OR cra) cyclist ) OR ( (trae OR prae) cyclist ))*.
