With the rapid development of the Internet and WWW, numerous on-line resources are available due to efforts of research groups, companies, government agencies, and individuals all over the globe. How to provide an effective and efficient solution to access such a huge collection of resources for end users is a demanding issue, which is the major goal of federated search, also known as distributed information retrieval. In this section, we are going to discuss the two key issues involved, i.e., resource selection and especially result merging, with the assumption that partial overlap exists among different resources. In a sense, merging results from overlapping databases looks somewhat like the data fusion problem, in which results are obtained from identical databases.
