What are some considerations for optimizing the performance of a PHP-based search program for a website?

One consideration for optimizing the performance of a PHP-based search program for a website is to use indexing to speed up search queries. By creating indexes on the columns that are frequently searched, the database can quickly locate relevant data, reducing the time it takes to retrieve search results. 

// Example of creating an index on a column in a MySQL database table
$mysqli = new mysqli("localhost", "username", "password", "database");

// Create an index on the 'title' column in the 'articles' table
$mysqli->query("CREATE INDEX idx_title ON articles(title)");
