What do you mean by 'incremental'? Adding a single entry/document to an index?

public void indexSingleEntry (File indexFile, String id, String cat, String prob, String sol){
        IndexWriter writer = null;
        try {
            Analyzer analyzer = new GermanAnalyzer();
            writer = new IndexWriter(indexFile, analyzer, false);
            Document doc = new Document();
            doc.add(Field.Text("id", id));
            doc.add(Field.Text("category", cat));
            doc.add(Field.Text("problem", prob));
            doc.add(Field.UnStored("solution", sol));
            writer.addDocument(doc);

        }
        catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            if (null != writer) {
                try {
                    writer.close();
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }
    }
