In simple language, if I install and use Sphinx (GPLv2) on my co-located server for a commercial LAMP website do I need to buy a license?

Do I have to license Sphinx for a commercial website? I don't need to modify the code... just use it with MySQL.

• No.

  An important instance when a commercial license is not required generally occurs when one uses Sphinx for a Web site or a hosted service. For example, even if one provides a paid search services to their end users, a commercial license would not be required
