Class StempelFilter

Transforms the token stream as per the stemming algorithm.

Note: the input to the stemming filter must already be in lower case, so you will need to use Lucene.Net.Analysis.Core.LowerCaseFilter or Lucene.Net.Analysis.Core.LowerCaseTokenizer farther down the Lucene.Net.Analysis.Tokenizer chain in order for this to work properly!
