I listed a bunch over at https://seirdy.one/2021/03/10/search-engines-with-own-indexes.html https://seirdy.one/2021/03/10/search-engines-with-own-indexe..., and I'm always adding more. I first discovered Alexandria in early February: https://git.sr.ht/~seirdy/seirdy.one/commit/935b55f10f9024ee660d5b0f6c9f7e546db159d8 https://git.sr.ht/~seirdy/seirdy.one/commit/935b55f10f9024ee... Around the same time, I also discovered sengine.info, Artado, Entfer, and Siik. By sheer coincidence they all were mentioned to me or decided to crawl my site within the same couple weeks. So yes, from my perspective there have been more than a few new smaller engines getting active on the heels of bigger names like Neeva, Kagi, Brave Search, etc.
