Sample code

// ...
if (LuceneContainer.checkIndex(INDEXDIR)) {
   dataSource = new LuceneContainer(INDEXDIR);
   table.setContainerDataSource(dataSource);
   info = new Label("Index loaded, ready to make queries!");
}
//...
dataSource.search(query, LuceneContainer.DOC_IDENTIFIER, false);
table.setContainerDataSource(dataSource);
//...
        // ...
        luceneFacade = new LuceneFacade(LUCENE_VERSION, INDEX_DIR, UNIQUE_ID);

        // ...
        Button editButton = new Button("Edit");
        editButton.addListener(new Button.ClickListener() {
            private static final long serialVersionUID = -3593785583996681571L;

            public void buttonClick(ClickEvent event) {
                UPCEditor editor = new UPCEditor(EDITABLE_FIELDS);
                Object itemId = table.getValue();
                Item selectedItem = dataSource.getItem(itemId);
                String pojoId = selectedItem.getItemProperty(IDFIELD)
                        .getValue().toString();
                LuceneFacadeDemo app = LuceneFacadeDemo.getCurrent();
                UPCPojo pojo = (UPCPojo) app.getLuceneFacade().findPojo(
                        FacadeFactory.getFacade(), UPCPojo.class, pojoId);
                editor.setPojo(pojo);
                LuceneFacadeDemo.getCurrent().getMainWindow().addWindow(editor);
            }
        });

        // ...

        Button okButton = new Button("Ok");
        okButton.addListener(new Button.ClickListener() {
            private static final long serialVersionUID = -7931392904726598608L;

            public void buttonClick(ClickEvent event) {
                // commit changes
                upcForm.commit();
                LuceneFacadeDemo.getCurrent().getMainWindow().removeWindow(
                        UPCEditor.this);
                LuceneFacadeDemo.getCurrent().getLuceneFacade().storePojo(
                        FacadeFactory.getFacade(), pojo);
            }
