Stempel: Algorithmic Stemmer

Classes

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!

StempelPolishStemFilterFactory

Factory for StempelFilter using a Polish stemming table.

StempelStemmer

Stemmer class is a convenient facade for other stemmer-related classes. The core stemming algorithm and its implementation is taken verbatim from the Egothor project ( www.egothor.org ).

Even though the stemmer tables supplied in the distribution package are built for Polish language, there is nothing language-specific here.
