KeywordAnalyzer in 4.8.0 beta
I am looking at upgrading the following repo: https://github.com/themotleyfool/Lucene.Net.Linq/tree/v4_0
From Lucene.Net 3.0.3 to the latest 4 beta packages.
The first issue I have hit is that I can’t get this analyser to compile: https://github.com/themotleyfool/Lucene.Net.Linq/blob/v4_0/source/Lucene.Net.Linq/Analysis/CaseInsensitiveKeywordAnalyzer.cs
Because it derives from `KeywordAnalyzer` which is now sealed.
What should I be doing instead?
Many Thanks
Darrell

Darrell,
Refer to these StackOverflow answers:

You wouldn't extend an analyzer, because that would effectively mean wrapping one instance of TokenStreamResult inside of another. For performance reasons, it is better to copy the contents of an existing analyzer and modify it as required. This was a design decision that the Lucene team made that was carried over into Lucene.Net.
Thanks,

I think you should install this package for you project.
https://www.nuget.org/packages/Lucene.Net.Analysis.Common/
In the new version (4.8.0) ,'KeywordAnalyzer' has changed package.Now it is in Lucene.Net.Analysis.Common package.
