Honestly, it may not be at the level you are describing here now, but I have been overwhelmed by the ability I've had to find small figments of memories with Google search. For example, I had a faint memory of a movie I watched as 4 year old, and could only remember a few generic nouns describing it, and after a few minutes of searching I was able to pinpoint. This wasn't possible years ago, either because the search engine itself wasn't ready, or that the information simply wasn't on the web. Now both of those are true, and only becoming more so, so they are improving in tandem.
I'm pretty confident I can find something on the web by only knowing a few keys words.
