you can close the index, but the Garbage Collector still needs to 
reclaim the memory and it may be taking longer than your loop to do so.

I disagree or I don't understand. 

I can change the code as it is shown below. Now I must reopen the index to see the 
changes, but the memory problem remains. I realy don't know what I'm doing wrong, the 
code is so simple.
Jiri.
        ...
    public static void main(String[] args) throws IOException
    {
        Directory directory = create_index();
        for (int i = 1; i < 100; i++) {
            System.err.println("loop " + i + ", index version: " + 
IndexReader.getCurrentVersion(directory));
            search_index(directory);
            add_to_index(directory, i);
        }
    }
    private static void add_to_index(Directory directory, int i) throws IOException
    {
        IndexWriter writer = new IndexWriter(directory, new StandardAnalyzer(), false);
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        Document doc = new Document();
        doc.add(Field.Keyword("date", df.format(new 
Date(System.currentTimeMillis()))));
        doc.add(Field.Keyword("id", "CD" + String.valueOf(i)));
        doc.add(Field.Text("text", "Tohle neni text " + i));
        writer.addDocument(doc);
        System.err.println("index size: " + writer.docCount());
        writer.close();
    }
        ...

You should reuse your old index (as eg an application variable) unless 
it has changed - use getCurrentVersion to check the index for updates. 
This has come up before.
