OK, fair warning, this didn't work for me, though the problem may be either me, my reading of the instructions, something undocumented, or a glitch on the site. But it's an interesting enough idea that I'm passing it along anyhow. The idea here is that you can create a Google spreadsheet of tagged open educational resources and connect it with an online search service (called Elasticsearch) to search and browse your OER collection (I tried using appbase.io, but there are other cloud Elasticsearch providers out there. This may seem pretty basic, but I can easily imagine this basic application extended with, eg., content-harvesting functions, content summarizers, automated metadata generators, or other analytics services. What would be great is if this worked just by following simple instructions, without programming needed, but we're not quite there yet.
