You can only search exact usernames. So yes you can but the lack of an exact match still doesn't mean they will let you use your desired username. Using the previous example, if you searched the username the new user wanted, "Darkthought the Nightwing", it shows as unused. However, if you searched "Darkthought the nightwing" (notice the lowercase "n"), then it shows that the user does exist. The best bet is to come up with a second choice name and try that.
