Search in the roadmap is exciting. It'd often be great to constrain search to just the pages I already visited, and there's never an option to do so. And because it's not a full index of the web with billions of pages, this search could be _a lot_ smarter than general purpose search, since it could actually understand both the pages and the query better in a completely privacy-protecting way using recent techniques that are cost prohibitive if you have to run at 1M QPS. Make it so!
