Description
It would be convenient to have a TypeTokenFilter that filters tokens by its type, either with an exclude or include list. This might be a stupid thing to provide for people who use Lucene directly, but it would be very useful to later expose it to Solr and other Lucene-backed search solutions.

Patch looks good Tommaso: though I think stopTypes should be Set<String> because type attribute is a string.
Thanks Robert, you're right.
Updated patch attached.
updated patch with unit test
Hi Tommaso!
Nice work, I will commit this if nobody objects!
Thanks Uwe for taking care of it 
Committed trunk revision: 1234396
Committed 3.x revision: 1234397
Tommaso: Can you maybe provide a Solr factory in a separate Solr issue (or reopen this one)?
Sure Uwe, I'll open a new one for the related Solr factory
Uwe looks like you committed as LUCENE-3121 by accident...
Oh did I use wrong issue number? I'll fix commit messages!
Fixed, I am so sorr!. Was a copypaste error from previous CHANGES.txt entry, I duplicated to edit. I used the entry as commit message with wrong issue number, too. That's how it happened 
A very basic TypeTokenFilter can be implemented extending a FilteringTokenFilter where the accept() method checks on a stopType set for the typeAttribute.type() matching.
