How to create a new Lucene Document in Version.Lucene_35?

Any idea how to create a lucene Document from Strings or Textfiles or Directories in the new version of Lucene? Where can i find the API in the current lucene version??

previously in 2_9_4, i could:

IndexWriter = writer = new IndexWriter(indexDir, config);
add(writer, "Lucene");

or even in 3_0_2:

IndexWriter = writer = new IndexWriter(indexDir, config);
writer.addDocument(createDocument("lucene");

But now i'm clueless how the add document goes. How do i add textfile as a lucene Document? or even a Directory of textfiles?

Hm, among the 3.5 examples I find this (http://lucene.apache.org/java/3_5_0/api/contrib-icu/index.html):

        Collator collator = Collator.getInstance(new Locale("ar"));  
        ICUCollationKeyAnalyzer analyzer = new
        ICUCollationKeyAnalyzer(collator);
        RAMDirectory ramDir = new RAMDirectory();   
        IndexWriter writer = new IndexWriter(ramDir, analyzer, true, IndexWriter.MaxFieldLength.LIMITED);   
        Document doc = new Document();   
        doc.add(new Field("content","\u0633\u0627\u0628", Field.Store.YES,Field.Index.ANALYZED));   
        writer.addDocument(doc);   
        writer.close();

The IndexWriter is there (http://lucene.apache.org/java/3_5_0/api/core/index.html)...

Are you sure you imported all necessary libraries?
