Mercury relay holds Wikipedia and Project Gutenberg events. When you pull in a wiki event, it queries for linked wiki events in the background, so you're slowly growing your own local wiki backup 😁
I search through either a d-tag
d:"{title}"
or if i don't know the exact name, i'll use an external search engin to find it, copy the link from Wikipedia or Gutenberg and enter it in the search like
s:"{url}"
