get a Word in FuzzyQuery

Hello guys. I'm working with FuzzyQuery and I a have a doubt: I would like
the lucene, return to me the correct word instead of me returning the
document, for example:

query = Brazil
document = "Brazil is a big country"

with this code:

[code]
Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_CURRENT);  
  
Directory directory = new RAMDirectory();  
  
IndexWriter iwriter = new IndexWriter(directory, analyzer, true, new
IndexWriter.MaxFieldLength(25000));  
  
Document doc;  
  
for (int i = 0; i < list.size(); i++) {  
    doc = new Document();  
    doc.add(new Field("fieldname", list.get(i), Field.Store.YES,
Field.Index.ANALYZED));  
    iwriter.addDocument(doc);  
}  
  
iwriter.close();  
  
IndexSearcher isearcher = new IndexSearcher(directory);  
  
Term term = new Term("fieldname", s);  
  
FuzzyQuery query = new FuzzyQuery(term, 0.75f, 0);
  
TopScoreDocCollector collector = TopScoreDocCollector.create(10, true);  
isearcher.search(query, collector);  
  
ScoreDoc[] hits = collector.topDocs().scoreDocs;  
for (int i = 0; i < hits.length; i++) {  
    Document hitDoc = isearcher.doc(hits[i].doc);  
    listr.add(hitDoc.get("fieldname"));  
}  
  
isearcher.close();  
directory.close();  
  
for (int i = 0 ; i < listr.size() ; i++ ) {  
    resp.add(listr.get(i));//melhorar método para fazer busca dentro de
busca  
}  
  
  
return resp;  
[/code]

The lucene, return to me the entire document ie "Brazil is a big country",
but I just wanted the word "Brazil". Somebody can help me?

Sorry, but you need to ask this on the Lucene user list.
