Yes, Elasticsearch is an option, but many (most?) instances haven't installed it, including mine.

And even when it is installed, it doesn't do what I want.

In addition to my own posts, I want to index the public posts of those I follow, and I want to organize by topics that aren't found in the text of the post, and I want to "follow" search terms similar to how the latest Masto allows following hashtags.

None of this is available with Elasticsearch even if it was enabled on my instance.
