Ian,

Did you ever figure this out. I'm poking around but I can't find any example nor 
get it to work. I'm stuck at creating the SynonymMap.

Thanks,

Re: How SynonymFilter works?

I didn't know that SynonymMap had gone all FST.

Looks like you need something along these lines

String base1 = "fast";
String syn1 = "rapid";
String base2 = "slow";
String syn2 = "sluggish";

SynonymMap.Builder sb = new SynonymMap.Builder(true);
sb.add(new CharsRef(base1), new CharsRef(syn1), true);
sb.add(new CharsRef(base2), new CharsRef(syn2), true);
SynonymMap smap = sb.build();


Hope that helps.  There may be an easier way.  Have you tried looking
at the source code/test cases?
