You should open a bug entry in Bugzilla and then attach your code to
it, with ASL on top.
However, there is a PorterStemFilter built into Lucene.  Please compare 
with that.

                1º Why does it change 'y' to 'i' character using parser

                    Instance: study -> studi

That's what stemmers do.  This allows queries for "study" and
"studies"
to match the same documents, for example.

                2º In our case, Lucene has searches 50 hits and is showed
the first one only.
                    If I comment new PorterStemFilter(ts) from our Analyzer
class. All 50 hits is showed. Why?
You haven't provided enough information.   Please provide a simple
short example that shows one document (that currently does not get
found) being indexed along with the code for your analyzer, along
with
a sample query that should match but doesn't.
Erik,
I just this week joined the mailing list, and on this topic thought
I'd mention that I've rewritten the PorterStemmer Java class,
cleaning
up whitespace and predeclaring all the Strings for better
performance.
It passes the file-in file-out test provided by Martin Porter (iow,
no change from the existing algorithm). The source for mine was taken
from his site -- I'm not sure of the origin of the one in Lucene. I
could also add an Apache license to the top.
What would I need to do to contribute this file? Just fill out the
ASF IP form and then commit the file in CVS?
Thanks,
Murray

    [International terrorism] is a fantasy that has been exaggerated
    and distorted by politicians. It is a dark illusion that has
    spread unquestioned through governments around the world, the
    security services, and the international media. In an age when
    all the grand ideas have lost credibility, fear of a phantom
    enemy is all the politicians have left to maintain their power."
