  • Swish::IN_FILE

  • Swish::IN_TITLE

  • Swish::IN_HEAD

Example 2521. Basic SwishSearch->setStructure() example


try {

$swish = new Swish("index.swish-e");
$search = $swish->prepare();

$results = $search->execute("time");
"First query found: ", $results->hits, " hits\n";

$search->setStructure(Swish::IN_TITLE|Swish::IN_HEAD); //search in title and head
$results = $search->execute("time");
"Second query found: ", $results->hits, " hits\n";

$search->setStructure(Swish::IN_ALL); //search in whole document, the default value
$results = $search->execute("time");
"Third query found: ", $results->hits, " hits\n";

} catch (
SwishException $e) {
$e->getMessage(), "\n";


The above example will output something similar to:

First query found: 5 hits
Second query found: 0 hits
Third query found: 5 hits
