Thread:Project:Support desk/Creating multisite search using search-redirect.php script

Hello! I want to create a multisite structure like wikipedia.org, built on the mediawiki engine. It has to look as:

mysite.com ru.mysite.com en.mysite.com etc. .. I am going to create a main page like wikipedia.org. In other words, it is a static page consisting hyperlinks to ru.mysite.com, en.mysite.com and so on... But! There is 'Search' button. That search engine use search-redirect.php script. Where I can get this script and what I have to do else, that my search engine begin works in all sites? Thank you for help!
