Search computing is a novel discipline whose goal is to answer complex, multi-domain queries. Such queries typically require combining in their results domain knowledge extracted from multiple Web resources; therefore, conventional crawling and indexing techniques, which look at individual Web pages, are not adequate for them. In this paper, we sketch the main characteristics of search computing and we highlight how various classical computer science disciplines - including software engineering, Web engineering, service-oriented architectures, data management, and human-computing interaction - are challenged by the search computing approach.
