I played around with this for a bit and figured out the issue. Note: this is also an issue on .net 4.0/visual studio 2010.
There is a lucene 18.104.22.168 (deprecated) nuget package but it won't work since the assembly it is not signed. To obtain the correct signed assembly, download and save the following file: https://github.com/leemhenson/nhibernate-contrib/raw/master/src/NHibernate.Search/lib/Lucene.Net.dll
and reference it in your project and it should start working.
