Estimate document count (HTTP)

For details about additional languages, see:

Estimates the number of documents in a collection.

This method only returns an estimated count. It is an alternative to getting an exact count, which is a slow and expensive operation.

The estimated count is based on current system statistics at the time the request is received by the database server.
