Hi,
I think that displaying the payload (if one exists) of each token
in the analysis.jsp would be beneficial. My simple solution was to
add a row to the existing table, convert the Payload byte array to a
String and simple print the results. I opened SOLR-522 to this
effect.
There is a PayloadHelper class in Lucene that has decode/encode
float and int methods. Any ideas on how Payloads might be uniformly
decoded into something readable/debugable from the gui? I think
bytes to String will give enough of a clue to be helpful.
Similarity.scorePayload(), if defined, should be the commonly-used
method (at least, that's what I do):
public float scorePayload(byte [] payload, int offset, int length) {
assert length == 4;
int accum = ((payload[0+offset]&0xff)) |
((payload[1+offset]&0xff)<<8) |
((payload[2+offset]&0xff)<<16) |
((payload[3+offset]&0xff)<<24);
return Float.intBitsToFloat(accum);
}
