With the rapid growth and deployment of the distributed databases over the Internet,it calls for new efficient search method over multiple structured data sources.This paper proposes a new keyword-search method for effective database selection using inverted lists.The method can achieve a high interactive speed and thus can improve user experiences.This method has been implemented on airticket-search systems,and experimental results show that it achieves high search performance.For large scale data,a min-hash based algorithm is adopted to select highly relevant data sources,which can improve the performance and achieve high precision.
