Search not working

I don’t know what I’m missing here. When I click on the magnifying glass I will find nothing. Shouldn’t there be a list of documents that contain my key words? I use Scrivener for some months now.
Anyways, I attached a screen shot. I searched for “Template” and got 0 results

Oh well, I resolved it myself. I didn’t see that tiny little arrow. It seems I had selected something wrong. Select “all” did the trick.
