I'm trying to figure out where Lucene.Net.Highlight.dll and the corresponding formatting classes (such as SimpleHTMLFormatter) have gone to.
The last time I downloaded Lucene.Net this assembly was packaged up in the zip file, however this isn't the case with the latest download I could find and I couldn't find any other references to it on this page, or any other page for that matter.
Does anyone know where it is hiding?
There is no binary releases of the recent Lucene.Net versions.
You will have to check it out from : https://svn.apache.org/repos/asf/lucene/lucene.net/trunk/C#/contrib/Highlighter.Net using SVN and build the DLL yourself.
Update
The contrib package can now be reliably downloaded via Nuget, in binary release.
The Highlighter is now part of the Lucene.Contrib package in NuGet.
