Lucenenet 4.8.0.0 Highlighting Example

Question

So I want to use the Lucene Highlighter, and I came across this example:

http://www.programcreek.com/java-api-examples/index.php?api=org.apache.lucene.search.highlight.Highlighter

The problem is, I'm using a newer version of Lucene which doesn't seem to have the QueryScorer class, and other things. I'm using Lucenenet 4.8.0.0 as shown here. So I'm wondering how I can do this in this version of Lucene.
