Hmm? Masto comes with decent self-search now, you don't need to build it.
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.
