Php search engine for a site

[wikipoemes]

I have a French based language site: http://www.wikipoemes.com/ with articles on different categories.

I want to implement a simple php search engine for my website on pages like this on the top right corner:
http://www.wikipoemes.com/poemes/pierre-de-ronsard/index.php

Note: I keep all texts (title, body articles) on a mysql database.

Is there a possibility to integrate Google Site Search?

How can i do that?
I need some code suggestions, to make this script run fast.

Thanks all,

Here is a search tutorial I wrote with a little bit of modification it will work as a search for you.
