What best practices should be followed when implementing a search feature in PHP to ensure efficient sorting and filtering of search results based on relevance?

When implementing a search feature in PHP, it is important to ensure efficient sorting and filtering of search results based on relevance. One best practice is to use SQL queries with proper indexing and optimization techniques to improve search performance. Additionally, consider implementing full-text search capabilities in your database to enhance search accuracy and relevance. 

// Example PHP code snippet for implementing a search feature with sorting and filtering based on relevance

// Connect to the database
$connection = new mysqli("localhost", "username", "password", "database");

// Perform a search query with sorting and filtering
$searchTerm = $_GET['search'];
$query = "SELECT * FROM products WHERE name LIKE '%$searchTerm%' ORDER BY relevance DESC";
$result = $connection->query($query);

// Display search results
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // Display search results
    }
} else {
    echo "No results found.";
}

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