CouchDB is a simple find

I have a database couchDB. and I want, as in mongodb, to find one element. something like db.find({user : "John"}) Is this the easiest way to do this?

If you have your queries predefined, you can use views to query your database.

It is also possible to use temporary views for special searches, but they are never recommended for use in production, since the index is not saved.

If you need anything else along the lines of full-text search, check out couchdb-lucene .

A similar alternative to pouchdb-find is also being developed for the db package.
