There's just one "portuguese" configuration in our standard set of text
search configurations.  The only things that are really language-specific
about it are the Snowball stemmer (to discard uninteresting word
terminations, such as plurals) and the stop-list of common words to
ignore.  It might be that neither of those are particularly specific to
one dialect of Portuguese --- at least, the upstream Snowball code/docs
don't seem to mention anything about that.

In any case, you could create your own modified configuration if you
don't like what the standard one does.  The stopword list, in particular,
is quite trivial to modify.
