Despite all the recent hype about the Mastodon social-media service, it doesn’t appear to be that useful for keyword search. For instance a search for keyword “research”, just now, found absolutely nothing…

Turns out that, though search is public (i.e. no sign-up required)…

if you search something in the search box of Mastodon, it will find only users or #hashtags. A more powerful search system will be implemented in the near future.

I did find the third-party service Social Search – Discover accounts across multiple Mastodon servers (‘instances’). This only searches the public account descriptions though. If ‘FluffyTwiddle’ is posting about “open access” but doesn’t have that in their description, you won’t discover them.
