Package net.sf.eos.lucene Description

εοs based on Lucene. This package contains abstractions for the index creation and index look up. To support a better decoupling and configuration, the core services will create over factories.

SimilarityFactory

In a concordance system the length of a document may not be crucial. The main implementation of the Lucene length of the document is considered. The shorter document is the more important document. To suppress this attitude the default similarity implementation is NormedLengthSimilarity which sets the NormedLengthSimilarity.lengthNorm(java.lang.String, int) always to 1.0f.

LuceneDocumentCreator

To decouple the creation of the Lucence documents use instances of LuceneDocumentCreator. The LuceneDocumentCreator.newInstance(net.sf.eos.config.Configuration) factory method creates a new instance.

AnalyzerProvider

Its also possible to replace the Lucene analyzer. User the AnalyzerSupplier with the AnalyzerSupplier.newInstance(net.sf.eos.config.Configuration) factory method to create a new instance.
