What are the key considerations when creating a script for a search/missing ad feature in PHP?

When creating a script for a search/missing ad feature in PHP, key considerations include designing a user-friendly search interface, implementing efficient search algorithms to retrieve relevant results, handling user input securely to prevent SQL injection attacks, and optimizing the script for performance to handle large datasets. 

// Sample PHP code for creating a search feature

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Process user input
$search_term = $_GET['search_term'];

// Secure input to prevent SQL injection
$search_term = mysqli_real_escape_string($conn, $search_term);

// Perform search query
$sql = "SELECT * FROM ads WHERE ad_title LIKE '%$search_term%' OR ad_description LIKE '%$search_term%'";
$result = $conn->query($sql);

// Display search results
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Title: " . $row["ad_title"]. " - Description: " . $row["ad_description"]. "<br>";
    }
} else {
    echo "No results found";
}

// Close database connection
$conn->close();
