Are there any best practices for integrating an internet search function into a website without reinventing the wheel?

Integrating an internet search function into a website can be achieved by utilizing existing search engines or APIs, such as Google Custom Search or Algolia. This allows for quick implementation without the need to build a search engine from scratch. By leveraging these tools, websites can provide users with accurate and relevant search results without reinventing the wheel. 

<?php
// Example code using Google Custom Search API
$search_query = $_GET['search_query'];
$api_key = 'YOUR_API_KEY';
$cx = 'YOUR_CX_CODE';

$url = 'https://www.googleapis.com/customsearch/v1?key=' . $api_key . '&cx=' . $cx . '&q=' . urlencode($search_query);

$response = file_get_contents($url);
$results = json_decode($response);

foreach ($results->items as $item) {
    echo '<a href="' . $item->link . '">' . $item->title . '</a><br>';
    echo $item->snippet . '<br><br>';
}
?>
