---------------------------------------

             Summary: Investigate using alternative ConcurrrentHashSet implementation
                 Key: LUCENENET-634
                 URL: https://issues.apache.org/jira/browse/LUCENENET-634
             Project: Lucene.Net
          Issue Type: Task
          Components: Lucene.Net Core
    Affects Versions: Lucene.Net 4.8.0
            Reporter: Shad Storhaug


There is a lower level implementation of ConcurrentHashSet available on NuGet that supports all of our target platforms:

https://github.com/i3arnon/ConcurrentHashSet/blob/master/src/ConcurrentHashSet/ConcurrentHashSet.cs

The only limitation is that it does not actually implement {{ISet<T>}}. I don't believe that will be a problem, though. But, since this collection is used directly in {{IndexReader}} it is worth looking into.
