Using PerFieldAnalyzerWrapper seems to be working for what I need!

On indexing:

        PerFieldAnalyzerWrapper wrapper = new PerFieldAnalyzerWrapper(new
StandardAnalyzer(Version.LUCENE_33));
        wrapper.addAnalyzer("nome", new MetaphoneReplacementAnalyzer());
        IndexWriterConfig indexWriterConfig = new
IndexWriterConfig(Version.LUCENE_33, wrapper);
        Directory directory = FSDirectory.open(new File(indexPath));
        IndexWriter indexWriter = new IndexWriter(directory,
indexWriterConfig);

On search:

        Directory directory = FSDirectory.open(new
File(lastIndexDir(Calendar.getInstance())));
        IndexSearcher is = new IndexSearcher(directory);
        PerFieldAnalyzerWrapper wrapper = new PerFieldAnalyzerWrapper(new
StandardAnalyzer(Version.LUCENE_33));
        wrapper.addAnalyzer("name", new MetaphoneReplacementAnalyzer());
        QueryParser parser = new QueryParser(Version.LUCENE_33, "name",
wrapper);
        Query query = parser.parse(expression);
        ScoreDoc[] hits = is.search(query, 1000).scoreDocs;

Does anyone know any other phonetic analyzer implementation? I'm using
MetaphoneReplacementAnalyzer from LIA examples.

I'm looking at lucene-contrib stuff at
http://lucene.apache.org/java/3_4_0/lucene-contrib/index.html but I can't
seem to find other phonetic analyzers.

Thanks!
