Two things: First, he covered that by saying searching by brand still had his "real" search results on page 2. Second, maybe you're super young, but Amazon used to be "good stuff", not just "hey, let's compete with eBay, on their level." What if you actually don't know the difference between "good" arrows and "bad" arrows? It used to be that Amazon had already made that call for you.
Amazon used to be the place you bought from without effort. "Of course Amazon's going to give me the best item for the best price" was the ubiquitous mindset.
Now the Amazon brand name is garbage (to me). Their prices are so mercurial you can't rely on them being even "average" and odds are they're even predatory (since it's just some random guy setting his selling price, not amazon nor MSRP).
"Fool and His Money" capitalism rules the Amazon Marketplace.
It's the worst part of eBay without the low expectations and transparency.
