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

             Summary: KNearestNeighborDocumentClassifier.knnSearch applies previous boosted
field's factor to subsequent unboosted fields
                 Key: LUCENE-7991
                 URL: https://issues.apache.org/jira/browse/LUCENE-7991
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Christine Poerschke
            Priority: Minor


When reading code noticed that in [KNearestNeighborClassifier|https://github.com/apache/lucene-solr/blob/releases/lucene-solr/7.0.1/lucene/classification/src/java/org/apache/lucene/classification/KNearestNeighborClassifier.java#L179-L182]
a neutral boost factor is restored but in [KNearestNeighborDocumentClassifier|https://github.com/apache/lucene-solr/blob/releases/lucene-solr/7.0.1/lucene/classification/src/java/org/apache/lucene/classification/document/KNearestNeighborDocumentClassifier.java#L126]
this currently does not happen. This seems unintended.
