When searching by URL pattern it's often useful to search by domain.

when spam hunting that's quite unhelpful sometimes [citation needed], spammers aren't notorious for getting little details like capitalisation right.

Can we have an option to make this operator case insensitive or just remove the case sensitivity altogether?

    Nice find, for domain-only search. Unfortunately, the quotes are needed when including slashes: url:*stackoverflow.com/a/1732454/* (link) versus url:"*stackoverflow.com/a/1732454/*" (link).
