Google Reader question

So why doesn't Google Reader have a search box?

I routinely read things about 3 hours before I need to somehow know/apply/share them, so that by the time I actually need the info I have long since forgotten which blog I saw it on.

So...ummm...hey, Google, can you please get working on that for me? I know it amounts to one search collection for each Google Reader user - but hey, I have google desktop so maybe you could just push it off on me to index. I'm cool with that.

It's just perplexing that the "search" company doesn't offer it for my self-selected information feeds, which I would think would already be fairly effective at slimming down the source to the most relevant info.

Just curious.
