What are some best practices for implementing a real-time search function on a website?

Implementing a real-time search function on a website involves using AJAX to send search queries to the server without reloading the page, and then updating the search results dynamically. To achieve this, you can create a PHP script that handles the search queries and returns the results in JSON format. 

// search.php

// Check if search term is provided
if(isset($_GET['searchTerm'])){
    $searchTerm = $_GET['searchTerm'];

    // Perform search operation (e.g. querying a database)
    $results = searchFunction($searchTerm);

    // Return results in JSON format
    header('Content-Type: application/json');
    echo json_encode($results);
}

// Function to perform search operation
function searchFunction($searchTerm){
    // Perform search operation here (e.g. querying a database)
    // Return search results
}
