Joomla! 2.5 offers two search options.

First, enable the Smart Search Plugin in the plugin manager. Then, if you are using the Basic Search Module replace it with the Smart Search Module. Finally, if you have already created content, go to the Smart Search component in your site administrator and click the Index icon.
