Abstract:

The traditional database retrieval has a lot of problems, such as the slower retrieval speed, the incomplete results, and disorderly retrieval results and so on. This paper designs a database index structure based on the Lucene index structure, the full text retrieval tool and puts forward the concept of record inverted index list. So Website can be retrieved by the keywords in the index library, not following the traditional sequential search way, which greatly improves the retrieval efficiency. At the same time, experimental results show that the database fulltext retrieval basedLucene has the advantages of high recall and the orderly retrieval results.

Key words: inverted index, Lucene index, fulltext retrieval, index structure
