All Implemented Interfaces:

Cloneable

public class SearchTravRetLoadFieldSelectorTask
extends SearchTravTask

Search and Traverse and Retrieve docs task using a SetBasedFieldSelector.

Note: This task reuses the reader if it is already open. Otherwise a reader is opened at start and closed at the end.

Takes optional param: comma separated list of Fields to load.

Other side effects: counts additional 1 (record) for each traversed hit, and 1 more for each retrieved (non null) document.
