[jira] [Created] (LUCENE-4782) Let the NaiveBayes classifier have a fallback docCount method if codec doesn't support Terms#docCount()

Tommaso Teofili created LUCENE-4782:
---------------------------------------

             Summary: Let the NaiveBayes classifier have a fallback docCount method if codec doesn't support Terms#docCount()
                 Key: LUCENE-4782
                 URL: https://issues.apache.org/jira/browse/LUCENE-4782
             Project: Lucene - Core
          Issue Type: Bug
          Components: modules/classification
            Reporter: Tommaso Teofili
             Fix For: 4.2, 5.0


In _SimpleNaiveBayesClassifier_ _docsWithClassSize_ variable is initialized to _MultiFields.getTerms(this.atomicReader, this.classFieldName).getDocCount()_ which may be -1 if the codec doesn't support doc counts, therefore there should be an alternative way to initialize such a variable with the documents count.
