The Design And Implementation Of Online Shopping Search System

The system is mainly using the open source information retrieval tool library of Java Lucene, to research and develop of online shopping system. At the purpose of simplifying the current mobile search system with the drawbacks of a large and redundant, we focus on developing a much more professional online shopping system and providing excellent support for mobile phone users. The project is mainly divided into three parts:crawl web date from the shopping website, extract information from the crawler side, mobile search and index engine. Searching and index engine is the core of this project. This part is also divided into three parts, including the search, indexing part and the distribution for the data. Of course, this system is primary using the Lucene index to establish appropriate index directory, and then write the data with the format of file into the appropriate directory, actually improve the indexing and querying performance. The project uses the standard software development process to develop, from requirement analysis, outline design, detailed design, coding and unit testing, functional testing, integration testing. The quality of the entire project development and the schedule time are controllable.The paper analyzes the project's various functional modules, covering data query and indexing for the front side and web crawling,web data extraction for the end side, and describe the relationship between the various modules, the interface call between different module. The overall framework of the project in this article has also been described. The performance of the system is very important. So during time of the development, we need to consider many aspects, such as query optimization, index optimization, and the distribution of data. The relevant technology for the system is also described.
