I wish there were a search engine that could figure out the groups the search results belong to. Sometimes when searching for swift programming language, a certain singer also makes an appearance. Or when searching for physics related things, I get that Olivia Newton John song.

To be honest, I think that I would actually want an engine that scrapes fewer sites but good sites and tries to understand them better. Also regular expressions.
