I don't think my comment implies we ditch digital search indexes. I just think Google as a replacement for properly curated search indexes is the problem here. For general web site searches Google is great but if you're looking for a particular topic it often comes up with sites that aren't even relevant (again my shortwave listening hobby is a great example of this problem). It's pretty hard to work just Google alone when you need a solid base to work from in terms of sites and documents for niche topics. It's why I tend to go back to books for my niche interests. You can't expect Google to handle every possible case because it won't do its primary well.
