    $search = $swish->prepare();

    $results = $search->execute("time");
    echo "First query found: ", $results->hits, " hits\n";

    $search->setStructure(Swish::IN_TITLE|Swish::IN_HEAD); //search in title and head
    $results = $search->execute("time");
    echo "Second query found: ", $results->hits, " hits\n";

    $search->setStructure(Swish::IN_ALL); //search in whole document, the default value
    $results = $search->execute("time");
    echo "Third query found: ", $results->hits, " hits\n";

} catch (SwishException $e) {
