Yes, unfortunately. Apps take time to show up in search results even after they are officially on the store. (The time before visibility, either in search results or even at a direct link, can vary by country as well.)

Yeah, the app store can be really glitchy the first couple hours after an app is released (our app once showed up in two spots at the same time on the top 100 list!)

Yep, it takes a bit of time for the search index(es) to be updated.

"Youtube Google" Seemed to work for me.
