I've written a simple phonetic token filter (and factory) based
on the Double Metaphone implementation in Jakarta Codecs to
contribute. Three questions:
1. Does this sound like a generally useful addition?
2. Should we have a Jira issue first?
3. This adds a depencency on the codecs jar. How do we add that
to the distro?
The code is very simple, but I need to learn the contribution
process and build some tests, so this won't happen in one day.

Sure!
Do you know if it is supposed to work for non-english languages? I'm
interested in testing it on French (and maybe German) texts, once your
patch is ready.

Double Metaphone has several rules for non-English words, but it
assumes English pronunciation. I think the biggest problem would
consonants that are silent or vowel sounds. For example, it codes
"Paris" as "PRS" instead of with a silent "s" as in French, and
"Jonas" as "JNS" where in German it would be pronounced "yonas".
And "Wim Winders" is coded as "AM ANTR", treating the "W" as a
vowel instead of a "V" sound.
It is worth a try. Most implementations of Double Metaphone are
well-commented, so you could change it for other languages.

Ok, I'll see if I find some time to test that, thanks for the clarifications!

Definitely useful.
If it's generally applicable enough and light weight enough then it
should go in the core. Otherwise it could go in contrib (which we
don't really have yet, but we will when the need arises).
This sounds like it should probably go in the core.

Yes, please.

It would go in the lib directory if it ends up in Solr proper.
