<?php
try {
    $swish = new Swish("index.swish-e");
    $search = $swish->prepare();
    $results = $search->execute("lost");
    var_dump($results->seekResult(0)); //this will succeed
    var_dump($results->seekResult(100)); //this will fail
} catch (SwishException $e) {
    echo "Error: ", $e->getMessage(), "\n";
}
?>
