] )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。使用本函数风险自担 。

query
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
