Abstract: As an information retrieval library written in Java, Lucene, with high performance and easy to scale, can easily add searching and indexing capabilities to applications. This paper discusses the vector space model used in Lucene, analyzes the structure of index files and ranking algorithm, and describes the compressing algorithm in Lucene. An experiment is done to test the indexing process of Lucene.

Key words: Lucene, vector space model, ranking algorithm, information retrieval
