Perhaps you should try some spelling variations:
competitive » competition
ccompetitiveness » ccompetitionness, scompetitiveness, competitivenest, competiveness, ccompetitivenests, cscompetitivenesss, ccompetitionss
competitivenes » competitionnes, competitivenest, scompetitiveness, competitions
competitiveness » competitionness, competitivenests, scompetitivenesss, competitionss
competitiviness » scompetitiveness, competitivenest, competiveness

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((competitive OR (ccompetitiveness OR competitivenes)) OR competitiveness) OR competitiviness)~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((competitive or (ccompetitiveness OR competitivenes)) or competitiveness) or competitiviness)~".
• Adding a wildcard symbol may retrieve word variants: (((competitive or (ccompetitiveness OR competitivenes)) or competitiveness) or competitiviness)*.
