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
