Hi Nathan,

There is an option of disabling public search ie, if his/her profile public search disabled means we can't find by their profile by simply searching, definitely we need their URL
and also there is the possibility of not having their original names, she might have kept her nick name or anything else..
If you know her mail id, do a search by using her mail id.
