void |
normalize(float queryNorm,
float boost)
Assigns the query normalization factor and boost from parent queries to this.

public float getValueForNormalization()
Similarity.SimWeight
NOTE: a Similarity implementation might not use any query normalization at all, it's not required. However, if it wants to participate in query normalization, it can return a value here.
getValueForNormalization
in class Similarity.SimWeight
public void normalize(float queryNorm, float boost)
Similarity.SimWeight
NOTE: a Similarity implementation might not use this normalized value at all, it's not required. However, it's usually a good idea to at least incorporate the boost into its score.
NOTE: If this method is called several times, it behaves as if only the last call was performed.
