as body with the following attributes:

@RESTBODYPARAM{collection,string,required, string}
The identifier or name of the collection to query.

Returns a JSON object with the document stored in the attribute
*document* if the collection contains at least one document. If
the collection is empty, the *document* attribute contains null.

@RESTRETURNCODES

@RESTRETURNCODE{200}
is returned if the query was executed successfully.

@RESTRETURNCODE{400}
is returned if the body does not contain a valid JSON representation of a
query. The response body contains an error document in this case.

@RESTRETURNCODE{404}
is returned if the collection specified by *collection* is unknown.  The
response body contains an error document in this case.
