Joomla Search Plugin
Hi Joomla experts !

I need asap a simply Joomla Search Plugin.
I like to include in the default Joomla Search feature in advance search a new table in MySQL db.
Example: I create a table called jos_travel an when I use the default Joomla search in advance mode, I like to have the option to choose “TRAVEL” do get listings.

Details how to create a Joomla plugin is here:

thanks
