This tutorial is intended for developers using MySQL
(http://www.MySQL.com/) and PHP
(http://www.php.net) who want to create a
searchable database of some sort of textual data. It will focus on the
Full-text capabilities presented by MySQL, moving into the Boolean opportunities
that are presented in the latest alpha version, 4.1, of MySQL.
Using directories to group articles by category is a great way
to help people to navigate through many articles. At some point, however,
someone will want to find all the articles that pertain to a certain
topic that may not have a directory of it’s own, or may span many
directories . This is what the search engine is for.
