             Summary: Document Classifiers to handle numeric fields
                 Key: LUCENE-7116
                 URL: https://issues.apache.org/jira/browse/LUCENE-7116
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/classification
    Affects Versions: 5.5
            Reporter: Alessandro Benedetti
            Priority: Minor


DocumentClassifiers should handle numeric fields.
Knn Document Classifier should be able to handle function queries( like the distance from the numeric value in input)  as boost factors on top of the MLT boolean query.
Investigations will follow with tentative design and patch

e.g.
input document has price:5

We can classify the document based on all the ones in the index, close to 5 as the price value.
