nutchserver is an alias for org.apache.nutch.api.NutchServer
NutchServer is not currently not available in Nutch 1.X. There is however a Jira ticket for backporting the REST API from Nutch 2.X to Nutch 1.X
Invoking the call to nutchserver ensures that a Nutch Server runs locally on a user defined port... by default this is set to 8081 if none is specified. This is a fully REST API for configuring and administering your Nutch crawler.
