I'll have to look into this and give you an answer for most things tomorrow after I get home. One thing I can answer for you now though...

(2) There are hundreds of names listed. It's not pretty or useful.
Clicking on a name goes to a profile, not their photos. On further digging, many of the names listed do not even have photos. Why would they be listed on search results for user name?
If you enter "joe" and don't check the 'Exact name' filed then it's going to check the database for all users that have "joe" in their username, get the corresponding userid, and then find all images posted according to those userids. Those usernames would still be included in the search. If you try searching for a partial username on your forums you should see that it will do the same thing and list all of the names even if that user hasn't posted.
