Why don't we have personalized search engines?

- Search as it is today sucks

- Google is an ad-engine, not a search engine

- SEO is gamed all the time

The end result is a search result that isn't that valuable.

Why isn't there a tool that allows me to:

- search good content I've read

- search curated (from other people I trust) content

- search books and other paid material I have bought

- search my notes (that are scattered throughout 5 apps)

All in one?
