I have complained about this a few times throughout the year. Each time I haven't had proof. I was finally motivated to make a new account on a completely different machine, grab the app, and try it for myself.

The thing is, if you search for it on the site, the same thing happens, HOWEVER, on the site, if you press enter, it will actually perform a search. On the APP, it selects the first result it pulls up and goes to it.
This ui design is frustrating. The search in the app should behave the same as the site. That is expected behavior. Or, perhaps allow the search in the app to actually search everything.
Pardon any perceived rudeness. It comes from me reporting this several times and being more or less brushed off. As it's not general release or anything, it hasn't been a massive deal. However, when I have to put extra instructions that people have to use the url bar and paste in the address of the splinterfaction page, that's a bit much.
