Zend Lucene Delete Document Issue

Question

I am trying to delete a document using zend lucene. The following is my code

$index = Zend_Search_Lucene::open('data/index');
foreach ($index->find('pk:' . $this->getId()) as $hit) {
        $index->delete($hit->id);
    }
$index->commit();

When I run this and checked my index folder there is a new file created like this _f4t5_1.del

But when I do a search, the deleted document is available in the search and also checked the

$index->numDocs();

This method also returns the same count before and after delete.

Any help is appreciated.

Answer 1

Just found the issue. The issue was due to a logical error in my code. After deleting I was calling another function which again added the document to the index. When I checked the document ID if found it to be different after deleting and that helped me to track the issue. Thanks for the help

Have you checked to make sure the documents are actually deleted.

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";
    }
}

Have you tried running index optimization:

Index optimization removes deleted documents and squeezes documents' IDs in to a smaller range. A document's internal id may therefore change during index optimization.
