The 3.x version of Lucene introduces lots of changes in its API. In 2.x we used IndexWriter API like this:

         Directory dir = FSDirectory.open(new File(indexDir));
        writer = new IndexWriter(dir,new StandardAnalyzer(Version.LUCENE_30),true,IndexWriter.MaxFieldLength.UNLIMITED);

I used the same code with 3.x version for one of my project. The tool was working fine. But my IDE(eclipse) told that some of the things are deprecated hmm…… I decided to dig the new API and I found that the above given code has to be changed to this :

        Directory indexDir =  FSDirectory.open(new File(strDirName));
        IndexWriterConfig confIndexWriter = new IndexWriterConfig(Version.LUCENE_CURRENT, analyzer);
        writer = new IndexWriter(indexDir, confIndexWriter); 

If you would like to use the "IndexWriter.MaxFieldLength.UNLIMITED" the IndexWriterConfig should be like: j ava IndexWriterConfig idxconfa = new IndexWriterConfig(Version.LUCENE_30, new LimitTokenCountAnalyzer(new StandardAnalyzer(Version.LUCENE_30), 1000000000));

The int ‘1000000000’ is set as maximum limit here. max(int) is the maximum you can set in IndexWriterConfig.
