Search result pagination — Zend Framework 2 2.4.2 documentation

Search result paginationΒΆ

As mentioned above, search result hit objects use lazy loading for stored document fields. When any stored field is accessed, the complete document is loaded.

Do not retrieve all documents if you actually need to work only with some portion of them. Go through the search results and store document IDs (and optionally the score) somewhere to retrieve documents from the index during the next script execution.

$cacheId = md5($query);

if (!$resultSet = $cache->load($cacheId)) {

        $resultSetEntry          = array();
        $resultSetEntry['id']    = $hit->id;
        $resultSetEntry['score'] = $hit->score;

        $resultSet[] = $resultSetEntry;
    }

    $cache->save($resultSet, $cacheId);

        'id'    => $resultSet[$resultId]['id'],
        'score' => $resultSet[$resultId]['score'],
        'doc'   => $index->getDocument($resultSet[$resultId]['id']),
