范例

Example #1 Basic SwishSearch::execute() example


<?php

try {

    $swish = new Swish("index.swish-e");
    $search = $swish->prepare();

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

    $results = $search->execute("new OR query");
    echo "Second query found: ", $results->hits, " hits\n";

} catch (SwishException $e) {
    echo $e->getMessage(), "\n";
}

?>

以上例程的输出类似于：

First query found: 2 hits
Second query found: 12 hits
