Engineering a Web search engine offering effective and efficient information retrieval is a challenging task. Mitos is a recently developed search engine that offers a wide spectrum of functionalities. A rather unusual design choice is that its index is based on an object-relational database system. This paper discusses the benefits and the drawbacks of this choice (compared to the classical inverted files), proposes three different database representations, and reports comparative experimental
