範例
Example#1 Basic SwishSearch->setStructure() example
<?php
try {
$swish = new Swish("index.swish-e");
$search = $swish->prepare();
$results = $search->execute("time");
echo "First query found: ", $results->hits, " hits\n";
$search->setStructure(Swish::IN_TITLE|Swish::IN_HEAD); //search in title and head
$results = $search->execute("time");
echo "Second query found: ", $results->hits, " hits\n";
$search->setStructure(Swish::IN_ALL); //search in whole document, the default value
$results = $search->execute("time");
echo "Third query found: ", $results->hits, " hits\n";
} catch (SwishException $e) {
echo $e->getMessage(), "\n";
}
?>
上例的輸出類似於：
First query found: 5 hits Second query found: 0 hits Third query found: 5 hits
