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
