How about adding a new paramer to Similarity.scorePayload( ) ?

[wuqi]

Hi,
I want to customize a new Similarity class which need to adopt payload 
information.The current definition of scorePayload is below:
    "public float scorePayload(String fieldName, byte [] payload, int offset, 
int length)"
I have a problem when using this function.In case we have two 
BoostingTermQuery:  
   BoostingTermQuery #1:   fieldName="Country" and  fieldValue= "America"
   BoostingTermQuery #2:   fieldName="Country" and  fieldValue="China"
and the the information of one payloads looks like this:
  payload: {new York,san Jose,Chicago}
of course,query #1 should get a higher payPayload score.But current interface 
prevent us from sending fieldValue information to scorePayload function. So 
maybe we should add a new interface like
   public float scorePayload(String fielName,String value,byte[] payload,int 
offset,int length)
and Boosting Query also need to be changed accordingly.

Thanks
