// document frequencies. If an value higher than 1 is specified
// then fractional can not be specified. Defaults to 0.01f. If
// a term appears in more then half the docs then don't try to
// correct it. This really shouldn't kick in much because we're
// not looking for misspellings. We're looking for phrases that
