SwishSearch->execute — Execute the search and get the results
此函数是实验性的。 此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本扩展风险自担 。
Searches the index file(s) based on the parameters set in the search object.
The query string is an optional parameter, it can be also set using Swish->prepare() method. The query string is preserved between executions, so you can set it once, but execute the search multiple times.
Returns SwishResults object.
Throws SwishException on error.
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
