Dont return 1 for tf...just return the tf straight with no
changes...return freq. For everything else return 1. After that
OMIT_NORMS should work. If you want to try a custom reader:
public class FakeNormsIndexReader extends FilterIndexReader {
byte[] ones = SegmentReader.createFakeNorms(maxDoc());
public FakeNormsIndexReader(IndexReader in) {
super(in);
}
public synchronized byte[] norms(String field) throws IOException {
System.out.println("returning fake norms...");
return ones;
}
public synchronized void norms(String field, byte[] result, int
offset) {
System.out.println("writing fake norms...");
System.arraycopy(ones, 0, result, offset, maxDoc());
}
}
The beauty of this reader is that you can flip between it and your
custom similarity and Lucene's default implementations live on the same
index.

I got the thing abou the OMMIT_NORMS and I tried to do it by calling
Field.setOmitNorms(true); before adding a field in the index. After that I
re-indexed my collection but still not making any difference.
Tell me if I got it right. The second solution that you followed is building
a custom FilteredIndexReader and implement these 2 functions :
byte[] norms(String field)
void norms(String field, byte[] result, int offset)
Did I get it right?
Thank you and excuse me for continuously asking the same thing.

Prob doesn't have great keyword for finding it. That should get you
going though. Let me know if you have any questions.
