@nickva thank you very much for your response. A "live query" would be a
very useful feature for front-end app developers.
I have [successfully implemented
this](https://github.com/colinskow/pouchdb-live-find), but it requires
listening to the entire changes feed. So my solution would not be entirely
practical with a noisy database.
Would it be practical to maintain state of the query in a `_design`,
`_replication`, or `_live_query` doc so the front end can maintain a live list
of docs that match that query without having to listen to other noise?
