synonym token types and ranking

[Uri Boness]

Hi,

I've noticed that currently the SynonymFilter replaces the original 
token with the configured tokens list (which includes the original 
matched token) and each one of these tokens is of type "word". Wouldn't 
it make more sense to only mark the original token as type "word" and 
the the other tokens as "synonym" types? In addition, once payloads are 
integrated with Solr, it would be nice if it would be possible to 
configure a payload for synonyms. One of the requirements we're 
currently facing in our project is that matches on synonyms should weigh 
less than exact matches.

cheers,
Uri
