XMLibrary search:: An XML search engine oriented to digital libraries

The increase in the amount of data available in digital libraries calls for the development of search engines that allow the users to find quickly and effectively what they are looking for. The XML tagging makes possible the addition of structural information in digitized content. These metadata offer new opportunities to a wide variety of new services. This paper describes the requirements that a search engine inside a digital library should fulfill and it also presents a specific XML search engine architecture. This architecture is designed to index a large amount of text with structural tagging and to be web-available. The architecture has been developed and successfully tested at the Miguel de Cervantes Digital Library.
