Yii::import('ext.xyz.XyzClass');

Using 3rd party libraries
protected/vendors/Zend/Search/Lucene.php
Yii::import('application.vendors.*');
require once('Zend/Search/Lucene.php');

Once the above set up is ready, we can use the Lucene class in a controller action, like the
following:

Nice URl 
array(
'posts'=>'post/list',
'post/<id:nd+>'=>'post/read',
'post/<year:ndf4g>/<title>'=>'post/read',
)

1.Calling $this->createUrl('post/list') generates /index.php/posts. The rst rule
is applied.
2 Calling $this->createUrl('post/read',array('id'=>100)) generates /index.php/post/
100. The second rule is applied.
3 Calling $this->createUrl('post/read',array('year'=>2008,'title'=>'a sample post'))
generates /index.php/post/2008/a%20sample%20post. The third rule is applied.
4 Calling $this->createUrl('post/read') generates /index.php/post/read. None of
the rules is applied.
