What are some best practices for structuring a MySQL database for a search engine in PHP?

When structuring a MySQL database for a search engine in PHP, it is important to properly index the fields that will be used for searching to improve performance. Additionally, using full-text search indexes can help optimize search queries. It is also recommended to denormalize data where necessary to reduce the number of joins required for search queries.

// Example of creating a table with full-text search index in MySQL
CREATE TABLE products (
    id INT PRIMARY KEY,
    name VARCHAR(255),
    description TEXT,
    FULLTEXT(name, description)
);
