How To Create A Search Panel

My Model is basically coming out of a view , e.g

$model=Yii::app()->db->createCommand('SELECT * FROM vCustomer')->queryAll();

Now I want to ensure that when the data is searched, it should filter out the $model based on search

public function actionIndex()


		// renders the view file 'protected/views/site/index.php'

		// using the default layout 'protected/views/layouts/main.php'

		// $this->render('index');

		$model=new Vessel('search');

		$model->unsetAttributes();  // clear any default values
