Search blog in network sites page (/network/sites.php)

In the network sites page (/network/sites.php), there is a search bar that allows searching for a blog in the network. However, this only works if you type the exact path of the blog (including the "/") in the search bar... which is not very handy.
Isn't there any way/plugin that allows searching based on a part of the blog name, and not on the entire name ?

Thanks in advance for your answer,
Regards
