Ask YC: Why no search box on YC?

It's happened twice now. I read an amazing writing: poignat, timely, and oh so apropos: but, two weeks later it's memory filters up through the "time fog", and I need to send a link, and I spend 15m site:news.ycombinator.com "cogent(s)".

In the meantime, I'll make 'a post' so that I can find it through my 'threads'.
