How can the efficiency of a search engine on a PHP website be improved to ensure all terms are found?

To improve the efficiency of a search engine on a PHP website to ensure all terms are found, you can use full-text search capabilities provided by databases like MySQL. By utilizing full-text indexes and search functions, you can improve the accuracy and speed of search queries on your website.

// Example PHP code snippet using MySQL full-text search

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

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

// Perform a full-text search query
$search_query = "SELECT * FROM articles WHERE MATCH(title, content) AGAINST('search terms' IN BOOLEAN MODE)";
$result = $conn->query($search_query);

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

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