I've created a search engine, The Wild Hunt, with a focus on vintage computers. The crawling data is public and suggestions for improvement are welcome. The back end for the search engine is YaCy. I'm also watching the PeARS Project, which is planning a release of PeARS Federated very soon. Depending on what PeARS is like, we may try running both at the same time, or even switching to that. The engine could still use a lot of tweaking. When you notice flaws, please be sure to report them on the crawling page.
