---------------------------------------

             Summary: Allow DirectSpellchecker to use totalTermFrequency rather than docFrequency
                 Key: LUCENE-4813
                 URL: https://issues.apache.org/jira/browse/LUCENE-4813
             Project: Lucene - Core
          Issue Type: Bug
          Components: modules/spellchecker
    Affects Versions: 4.1
            Reporter: Simon Willnauer
             Fix For: 4.2, 5.0


we have a bunch of new statistics in on our term dictionaries that we should make use of where it makes sense. For DirectSpellChecker totalTermFreq and sumTotalTermFreq might be better suited for spell correction on top of a fulltext index than docFreq and maxDoc
