text intermedia: what's the purpose of ">0"?

In context intermedia, if I want to do a search I do something like: Select name from prospect where
CONTAINS(resume, ‘engineering') > 0;

I don't understand the purpose of ">0" as this query should find all the "names" where 'engineering' is appear in resume anyway. So what's the purpose of the score?

Thanks,
