Namespace Lucene.Net.Analysis.Stempel

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 LowerCaseFilter or LowerCaseTokenizer farther down the chain in order for this to work properly!

Factory for StempelFilter using a Polish stemming table.

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.
