I have several little sites that use the Mastodon API just sitting unfinished. Here's one that attempts to put a user friendly UI on the advanced search (elasticsearch) options if your server supports it.
"If your server supports it" is where I'm stuck. There's no /api/vX/instance or nodeinfo fields that identify if the server has it enabled.
A login is required to test for it...so I have to ask the user to login, then tell them LOL NO JK your instance doesn't support this.
