Php multi language search engine

[ecoduri]

 

 

I have a Romanian based language site: http://www.ecoduri.com with informations about different codes.

 

I implemented a simple php search engine for my website on pages like this on the right side of the site

http://www.ecoduri.com/coduri-siruta.php

 

I want to add a new radio box field to select language for displayed search results on diferent languages.

 

Is there a possibility to integrate Google Site Search with more languages?

How can i do that?

 

I need some code suggestions, to make this script run fast.

 

Thanks all,
