Example #1 Basic Swish::prepare() example

  <?php

 try {

     $swish  = new  Swish ( "index.swish-e" );
     $search  =  $swish -> prepare ( "search query" );
     $results  =  $search -> execute ();
    echo  "Found: " ,  $results -> hits ,  " hits\n" ;

     $results  =  $search -> execute ( "new search" );

    echo  "Found: " ,  $results -> hits ,  " hits\n" ;
