Search Sites in Network Admin doesn't return partial matches

[novasource]

Suppose I have a network enabled WordPress site, and it has a blog named /abcdef/. If I go to wp-admin/network/sites.php and then search on abc in the Search Sites box at top right, I get no matches. I only get a match if I type abcdef.

This seems unusual. The search box should return partial matches, including returning the abcdef blog if I search on any substring in its name.

You need to use explicit wildcards now. Try abc*
