    SolrQuery::collapse — Сворачивает набор результатов до одного документа на группу

    Описание

    publicSolrQuery::collapse(SolrCollapseFunction$collapseFunction): SolrQuery

    Сворачивает набор результатов в один документ для каждой группы, прежде чем он пересылает набор результатов остальным компонентам поиска.

    Таким образом, все последующие компоненты (фасетирование, выделение и т.д.) будут работать со свёрнутым набором результатов.

    Пример #1 Пример использования SolrQuery::collapse()

    <?php

    include "bootstrap.php";

    $options = array
    (
    'hostname' => SOLR_SERVER_HOSTNAME,
    'login' => SOLR_SERVER_USERNAME,
    'password' => SOLR_SERVER_PASSWORD,
    'port' => SOLR_SERVER_PORT,
    'path' => SOLR_SERVER_PATH
    );

    $client = new SolrClient($options);

    $query = new SolrQuery('*:*');

    $collapseFunction = new SolrCollapseFunction('manu_id_s');

    $collapseFunction
    ->setSize(2)
    ->    setNullPolicy(SolrCollapseFunction::NULLPOLICY_IGNORE);

    $query
    ->collapse($collapseFunction)
    ->    setRows(4);

    $queryResponse = $client->query($query);

    $response = $queryResponse->getResponse();

    print_r($response);

    ?>

    Вывод приведённого примера будет похож на:
