Ask HN: Why is Couchbase Server under-represented here?

While Couchbase Server looks like a viable alternative to MongoDB, CockroachDB, TiDB, or even Cassandra, I see very little discussion about it here on HN in the past few years.

Is there any reason for that? Is the technology not living up to the marketing? Is it not hipster enough?

It looks like a good technology stack with easy to use server administration and integrated features most app can use (e.g. full-text search). I am a bit surprised that it is not featured here.
