Retrieving a document count is similar to retrieving a result list. A Dialog structure contains a count link which takes a CountExpression structure. The difference compared to retrieving a result list is, that the client can specify a field name. In such a case the client gets the number of the occurances of each value of the specified field.

For testing purposes, a client might follow this link using an HTTP GET directly and can optionally specify an URI parameter fieldName denoting the database name of the field to count.
