Searching Sites in Network Admin Should Use Wildcards

[hurtige]

In a Multisite Network:

Searching on the Sites List does not follow the same pattern as the rest of the searching of Wordpress, in particular it does not return results for partial terms

Example

You have a list of sites such as "main site" and "subsite1"

None of the terms "sub", "site", or "subsite" return the site titled "subsite1"

in other words you must remember the exact name of the site to get it returned in the search which is a pain with large networks

It supports wildcard search if you add a * to your query, although I think it only adds the wildcard to the end. That is, sub* should fine "subsite1", but "*site*" won't. Not sure what exactly the reason is, although I have a feeling there probably is one.
