C# Class Lucene.Net.Index.ConcurrentMergeScheduler

A {@link MergeScheduler} that runs each merge using a separate thread, up until a maximum number of threads ({@link #setMaxThreadCount}) at which points merges are run in the foreground, serially. This is a simple way to use concurrency in the indexing process without having to create and manage application level threads.
