Ferret::Search::MultiSearcher

Summary

See Searcher for the methods that you can use on this object. A MultiSearcher is used to search multiple sub-searchers. The most efficient way to do this would be to open up an IndexReader on multiple directories and creating a Searcher with that. However, if you decide to implement a RemoteSearcher, the MultiSearcher can be used to search multiple machines at once.
