        1 => array( 
        "url"           => "http://ganeshhs.com/url-2",

        "articleId"      => 2)
);
foreach($articlesData as $articleData)
{  
    $doc = $lucene_search->getDocument();  

    $doc->addField($lucene_search->getField('Keyword', array('url',  $articleData["url"])));
    $doc->addField($lucene_search->getField('UnIndexed', array('articleId',  $articleData["articleId"])));
    $doc->addField($lucene_search->getField('UnIndexed', array('postedDateTime',  $articleData["postedDateTime"])));
    $doc->addField($lucene_search->getField('Text', array('title',  $articleData["title"])));
    $doc->addField($lucene_search->getField('UnStored', array('contents',  $articleData["contents"])));
    $doc->addField($lucene_search->getField('Text', array('category',  $articleData["category"]))); 
    $index->addDocument($doc);
}
$index->commit();

To retrieve a query:

$query = 'zend';
$results = $index->find($query);
if(empty($results)){
    echo 'empty';
}else{      
    foreach($results as $result){
        echo $result->url;
    }
}
