Search result pagination

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 retrive documents from the index during the next script execution.

Example #1 Search result pagination example

$cacheId = md5($query);
 
if (!$resultSet = $cache->load($cacheId)) {
    $hits = $index->find($query);
    $resultSet = array();
    foreach ($hits as $hit) {
        $resultSetEntry          = array();
        $resultSetEntry['id']    = $hit->id;
        $resultSetEntry['score'] = $hit->score;
 
        $resultSet[] = $resultSetEntry;
    }
 
    $cache->save($resultSet, $cacheId);
}
 
$publishedResultSet = array();
for ($resultId = $startId; $resultId < $endId; $resultId++) {
    $publishedResultSet[$resultId] = array(
        'id'    => $resultSet[$resultId]['id'],
        'score' => $resultSet[$resultId]['score'],
        'doc'   => $index->getDocument($resultSet[$resultId]['id']),
    );
}

This doesn't make any sense at all. What does this have to do with paginating search results? :-S

Very bad example...undefined variables...no real live context!!!

why encrypt / hash a query string? that first line doesn't make sense

ok ... hindsight being what it is ... you have to cache a search query in order for it to persist over various pages after submitting/passing search values to Paginator

still this documentation is pretty damn convoluted

given that i have successfully implemented the Paginator tool in a straight SQL query (no wildcard WHERE var='%keyword%' conditions) i understand how the Zend_Cache is necessary to persist the keyword over many page loads ... however Paginator isn't referenced once in the above example and i have no idea how to integrate the two ( Paginator and Zend_Cache ). another fail for ZF documentation

ongoing grieve with the zend cache ... if the $_POST values are destroyed when loading pages, how do you make the md5() value persist over page loads when using paginator to page through results of a mysql wildcard search? if i don't have the md5() value on subsequent page loads, how can i access the cached value in zend_cache()? why am i talking to myself? and why am i doing it on the internet?
