Right, I have managed to get the source code for lucene .net 2.1 and I have
identified part of the scoring method in DefaultSimilarity.cs
/// <summary>Implemented as <code>log(numDocs/(docFreq+1)) + 1</code>.
</summary>
public override float Idf(int docFreq, int numDocs)
{
return (float) (System.Math.Log(numDocs / (double)
(docFreq + 1)) + 1.0);
}
I knew this one existed because of a write up I read about the scoring, I am
just need to identify where the score is modified by the number of words in
the document, if I can remove that calculation, build the dll, then ill be
sorted.
Ill keep searching but if anyone knows please let me know, I am currently
stepping through the source code line by line as it runs to identify whats
going on.
Much appreciated.
