> 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.
