Thanks to both for response me!
What's a meta tag?
It's some thing of nutch, it isn't a lucene field?
I suppose that implementing IndexFilter.filter:
filter(Document doc, Parse parse, UTF8 url, CrawlDatum datum, Inlinks
inlinks)
I can add my field to a doc instance.
Well, seems that the way is to try, to crash, and to try again... :)
Thanks,
Ernesto.

You can't do it unless you write a plugin to parse a custom meta tag
called category.
I'm trying to do something like this now, but the plugin documentation
is horrible.

Hi Ernesto!
I know what you mean. Sometimes I get no answers too. Unfortunately,
I'm new
in nutch and lucene and I can't help you. Continue trying, the
comunity will
help you :).

Hi All
Please, some body can answer my questions?
I'm a nutch beginner, I hope that my questions/doubts are easy... ;)
Or if my email is wrong, tell me. Or confirm me if I'm in the right
way.
Thanks a lot!
