Anyone figure out a solid approach for searching within a community?

I want to discuss a topic, say a recent event like "Google Search will omit links to Canadian news sites in Canada". So I find communities where that topic might appear but I cannot search the contents of a community to see if that thread exists.

Has anyone figured out good approaches to searching in Lemmy? I mostly use mobile apps like Jeroba or Liftoff so my experience is limited to them.
