Lucene doesn't index file

[Enrico Morelli]

I'm trying to index a text file using the last Lucene version, but nothing happens.

I created a txt file with some phrases inside.

This is my code:

public static void main(String[] args) throws IOException, ParseException {
        Path path = FileSystems.getDefault().getPath("./index");
        Analyzer analyzer = new StandardAnalyzer();
        Directory directory = FSDirectory.open(path);
        IndexWriterConfig config = new IndexWriterConfig(analyzer);
        config.setOpenMode(IndexWriterConfig.OpenMode.CREATE);
        IndexWriter iwriter = new IndexWriter(directory, config);
        Document doc = new Document();
        String text = "This is the text to be indexed.";
        String file = "/tmp/text.txt";
        FieldType fieldType = new FieldType();
        fieldType.setStored(true);
        fieldType.toString();
        File f = new File(file);
        doc.add(new Field("contents", file.getBytes(), new FieldType(fieldType) ));

        doc.add(new Field("filename", f.getCanonicalPath(),  new FieldType(fieldType) ));
        iwriter.addDocument(doc);
        iwriter.close();


        // Now search the index:
        DirectoryReader ireader = DirectoryReader.open(directory);
        IndexSearcher isearcher = new IndexSearcher(ireader);
        // Parse a simple query that searches for "text":
        QueryParser parser = new QueryParser("contents", analyzer);
        Query query = parser.parse("tanto");
        ScoreDoc[] hits = isearcher.search(query, 100).scoreDocs;
        // Iterate through the results:
        System.out.println("hits len: " + hits.length);
        for (int i = 0; i < hits.length; i++) {
            Document hitDoc = isearcher.doc(hits[i].doc);
            System.out.println("This is the text to be indexed." + hitDoc.get("contents"));
        }
        ireader.close();
        directory.close();
        //IOUtils.rm(indexPath);

        }

The indexes were created, but the hits are every 0. I tried a lot of file reader methods, but nothing changes.
Where is the problem?

I generally use the Luke desktop app (which comes with Lucene, check the "luke" directory for shell scripts to run it) to inspect any Lucene indexes, to make sure they actually contain what I think they should contain.
