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" ;
}
?>
以上例程的输出类似于:
First query found: 5 hits Second query found: 0 hits Third query found: 5 hits
