Abstract


This paper presents a search engine of goods in the e-commerce system , explore and text retrieval technology , and the combination of database queries and their merchandise search engine . The combination of technology and database of full-text search support relevance ranking , to improve the retrieval speed , but also flexible query and commodity structured information and real-time information . Characteristics of the merchandise for the e-commerce system , this paper presents the optimization algorithm based on the sort of commodity structured information . The weight of this algorithm increase in indexing keywords commodities important structural information related calculation , to achieve the purpose of optimization Relevance Sort results . This optimization algorithm is simple , without increasing the complexity of the sorting algorithm , for certain types of query optimizer better . The drawback is that some specific types of queries basic optimization . The paper also proposed adaptive algorithm based on user interaction , optimized user data to sort results . This algorithm also in the experiments, the proposed implementation .
