It is really hard to decipher what is going on inside the good old
TFIDFSimilarity.
{code:title=TFIDFSimilarity.IDFStats.normalize|borderStyle=solid}
@Override
public void normalize(float queryNorm, float boost) {
this.boost = boost;
this.queryNorm = queryNorm;
queryWeight = queryNorm * boost * idf.getValue();
value = queryWeight * idf.getValue(); // idf for document
}
{code}
* Why query weight has a IDF multiplicand?
* Why TFIDFSimilarity.IDFStats#value is set to IDF square?
* Why TFIDFSimilarity.IDFStats#value is need even though we have
TFIDFSimilarity.IDFStats.idf.getValue();
* TFIDFSimilarity.TFIDFSimScorer#score returns tf(freq) * IDFStats.value which
looks tfxIDFxIDF to me.
