Interface TargetSelector<T>

public interface TargetSelector<T>

Allows adding extra targets that the federation searcher should federate to. For each federation search call, the federation searcher will call targetSelector.getTargets. Then, for each target, it will: 1) call modifyTargetQuery(target, query) 2) call modifyTargetResult(target, result)
