范例
Example #1 Basic SwishSearch::setSort() example
<?php
try {
$swish = new Swish ( "index.swish-e" );
$search = $swish -> prepare ();
$results = $search -> execute ( "time" );
echo "First query found: " , $results -> hits , " hits\n" ;
$i = 0 ;
while( $result = $results -> nextResult ()) {
echo "Hit #" , ++ $i , " - " , $result -> swishdocsize , " bytes\n" ;
}
$search -> setSort ( "swishdocsize desc" ); //sort by document size
$results = $search -> execute ( "time" );
echo "Second query found: " , $results -> hits , " hits\n" ;
$i = 0 ;
while( $result = $results -> nextResult ()) {
echo "Hit #" , ++ $i , " - " , $result -> swishdocsize , " bytes\n" ;
}
} catch ( SwishException $e ) {
echo $e -> getMessage (), "\n" ;
}
?> 以上例程的输出类似于：
First query found: 5 hits Hit #1 - 4261 bytes Hit #2 - 37937 bytes Hit #3 - 7126 bytes Hit #4 - 15427 bytes Hit #5 - 4768 bytes Second query found: 5 hits Hit #1 - 37937 bytes Hit #2 - 15427 bytes Hit #3 - 7126 bytes Hit #4 - 4768 bytes Hit #5 - 4261 bytes
