One of the features I like in ES that I haven’t seen in alternatives is “Percolate queries” (queries where you feed the service a document and it returns a list of queries that you’ve indexed that would match that document - basically inverting the whole process).

Does anyone know of any alternatives that support this use case?

Yes. Manticore Search does. Here's an interactive course[1] about it, it's a little bit outdated though. More info in the docs[2]
