Phillipe Ramalho updated LUCENE-2979:
-------------------------------------

    Attachment: LUCENE-2979_phillipe_ramalho_4_trunk.patch
                LUCENE-2979_phillipe_ramalho_4_3x.patch

Here is a patch that backports the new configuration API to 3.x. I did exactly 
as I described in my proposal and it seems to be working as expected. I changed 
the documentation as well (I hope I everything, can you double check that 
Adriano?).

I also created a simple example of how to use the new API in package.html and 
added to both 3.x and trunk.

Please, let me know if everything looks good and if I didn't break any API.

> The current configuration API is very complicated and inherit the concept 
> used by Attribute API to store token information in token streams. However, 
> the requirements for both (QP config and token stream) are not the same, so 
> they shouldn't be using the same thing.
> I propose to simplify QP config and make it less scary for people intending 
> to use contrib QP. The task is not difficult, it will just require a lot of 
> code change and figure out the best way to do it. That's why it's a good 
> candidate for a GSoC project.
> I would like to hear good proposals about how to make the API more friendly 
> and less scaring :)
