I built a system which also functions as a kind of search engine. I too built an application for HN: https://hnprofile.com/ https://hnprofile.com/ If you're interested, I'd be happy to discuss it as what I focused on was ranking content (not indexing exactly). Might be some interesting synergy. They system requires a fraction of the data of a regular search engine and is often more effective.
