Subject Re: Lucene.NET 4.8.0 status update
Date Fri, 07 Nov 2014 23:25:25 GMT
Yet another update -

Lucene.Net.Queries is now fully ported as well, and we are working on
porting the Analysis, Suggest and Codecs packages.

We will be happy for any extra hands for both porting help and fixing the
remaining tests in Core.
