Part of the fun is stumbling on awesome names by accident.
I've run into a lot of names (and still do) that I resell for a lot or that I keep.
If players could find where a name is by simply typing it in, the search would be boring. All good names would be gone and all we'd have left are average names and junk.
I know it's a huge inconvenience and as a name collector myself I'd of course like to find things very easily, but the way it is now new players have a shot at stumbling on a "gem" that no one else noticed.
I also have fun sometimes trawling through the search for great names.
Hopefully this helps everyone understand why some of us are not fans of the idea.
