The synonym filter does set the "type" attribute to TYPE_SYNONYM for
synonyms, so you could write your own token filter that "keeps" only tokens
with that type.
Try the Solr Admin "analysis" page to see how various terms are analyzed by
the synonym filter. It will show TYPE_SYNONYM.

Subject: Synonym Filter: Removing all original tokens, retain matched
synonyms
Hi,
Is there a way to do this?
Token_Input:
the fox jumped over the lazy dog
Synonym_Map:
fox => vulpes
dog => canine
Token_Output:
vulpes canine
So remove all tokens, but retain those matched against the synonym map
Cheers,
Dan
