Get lengthNorm of a field
Hi,
is there a possibility to retrieve the lengthNorm for all (or a
specific) fields in a specific document?
Regards,
Philippe

Thanks for the quick reply. I was searching for methods in
IndexSearcher. Therefore I did not find the norms method.

See IndexReader: public abstract byte[] norms(String field) throws IOException;
And Similarity: public float decodeNormValue(byte b) {
The byte[] is indexed by document id, and you can decode that into a
float value with a Similarity.
