Abstract
While search engine technology based on crawling and indexing, presented in Part II, dominates the market, a niche is open for search systems based on data integration technology. These systems either rely on other search engines as sources of information or directly access specialized data sources that are focused on given domains. Interest in such systems is growing with the increase of Web applications which offer simple query interfaces to domain-specific data sources. This chapter overviews the theory of rank-driven data integration and top-k query processing, and then focuses on meta-search and multi-domain search.
