Class NormValueSource


public class NormValueSource extends ValueSource
Function that returns the decoded norm for every document.

Note that the configured Similarity for the field must be a subclass of TFIDFSimilarity and the contribution of the TF needs to be 1 when the freq is 1 and the contribution of the IDF needs to be 1 when docFreq == docCount == 1.
