Are you setting the Similarity before indexing, too, on the IndexWriter?

Hello,
I'm trying to write a custom scorer that only uses the term
frequency function from the DefaultSimilarity class, the problem is
that documents with lower frequencies are returning with higher
scores than documents with higher frequencies. Here's the code:
searcher.setSimilarity(new DefaultSimilarity(){
public float lengthNorm(String field, int numTerms){
return 1;
}
public float idf(int docFreq, int numDocs){
return 1;
}
public float coord(int overlap, int maxoverlap){
return 1;
}
public float queryNorm(float sumOfSquaredWeights){
return 1;
}
public float sloppyFreq(int distance){
return 1;
}
});
Any idea why this wouldn't be working?
Sincerely,
Chris Salem
