Research of distributed index based on Lucene

Abstract

Inverted index is the mainstay technology for full-text retrieval, however, there exist some problems such as low efficiency of index construction, updating and high Maintenance cost. In order to improve the retrieval performance of large scale indexing, the strategy of distributed indexing is proposed in this paper. This paper gives a detailed description of building index structures using Map Reduce, and compares the performance of building index and query between distributed search system and central search system. Experimental results show that the proposed scheme greatly reduces the time of index construction and query time. © 2012 Springer-Verlag.
