Searching only in undeleted documents using zend lucene

Question

I am not new with zend lucene but I have a trouble with searching using it. I search in documents by numbers using below code:

$term = new Zend_Search_Lucene_Index_Term($id, $idFieldName);
$docIds  = $index->termDocs($term);
foreach ($docIds as $id) {
    $doc = $index->getDocument($id);
    echo $doc->artist_name;
}
$index->commit();

and deleting a document by number using below code:

$term = new Zend_Search_Lucene_Index_Term($id, $idFieldName);
$docIds  = $index->termDocs($term);
foreach ($docIds as $id) {

    $doc = $index->getDocument($id);
    $index->delete($doc->lyric_id);

}
$index->commit(); 

When I delete a document, $index->numDocs() display that the document is deleted because the returned value is not equals the returned value of $index->count(). but the problem is, after deleting the document, I can search in it yet and I can display the value of its fields.

I checked that after optimizing the indexes but the problem is live yet. I need to remove completely a document or search in the documents that are not deleted from indexes.

Loop through the search results and check if the document is deleted. If it is, remove it from the search results.

Zend_Search_Lucene::isDeleted($id) method may be used to check if a document is deleted.

for ($count = 0; $count < $index->maxDoc(); $count++) {
if ($index->isDeleted($count)) {
    echo "Document #$id is deleted.\n";
} }
