How do I handle multi-language or international site search using SQL?

The simplest approach is to create separate tables for each language, but this can become difficult to manage if you have a lot of languages. Alternatively, you can use a single table with a language column, making it more efficient.

Finally, the most sophisticated way is to use a database engine that supports internationalization (I18N), but it requires a lot of setup.

The best method for you will depend on your specific needs and requirements. Just make sure to test this function fully. A less-than-optimal site search can bring your traffic and conversions down.
