I think the YaCy dev hopes so ๐ค ~~But I'm not sure it's written to be "hyperscale" or scalable at all. It seems to be a monolithic thing with the indexer, search enginer, crawler, etc. all in one. My guess is: no~~
After some searching, there seems to have been an effort to rewrite YaCy in to microservers called YaCy Grid. Soooo maybe?
It's unfortunate that all the new "privacy searchengines" like duckduckgo, startpage, ecosia, qwant, and others, all decided to write their own new solution on top of Bing instead of participating in YaCy or some other opensource solution. Doesn't make sense to me and makes me trust them much less (but still more than google and bing individually).
