I spent probably 20 a few days ago trying to find the HN discussion for the ElasticSearch 1.0 release (as I'd remembered there being some useful comments there about using ES as a document store, but not their exact contents), and ended up with nothing. Ultimately, I ended up spending another 45 minutes on the general internet trying to piece together the bits of the comment I remembered.
With the new update, I tried the same query as I had, and it was immediately the very first result.
BRILLIANT.
