How SynonymFilter works?
Dear all
I am going to find out how SynonymFilter in Lucene-analyzers 3.5 works and what exactly its output tokens are.
Is there any sample code that shows how to fill SynonymMap and then use SynonymFilter to filter a sentence.
I appreciate any comment.
Thanks,
Atieh Soleimani

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?

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.

Did you get an answer to this? Looking at the lucene test cases can
be a good way of finding out things like this. Reading Lucene In
Action is also highly recommended. May not have the exact answer to
this question but will teach you how to find out.
