Traditional information search and retrieval systems crawl collections of URLs pointing to the physical locations of documents or web pages, index their content, and return a set of URLs in response to user queries. The users, however, require
more flexible, customizable, reliable and effective information search and retrieval systems. This paper presents an alternative approach by adopting the concepts of ‘virtual documents’ and ‘virtual URLs’ that utilize searchable component libraries created by extracting information from documents. This approach enables the design of information search and retrieval systems with enhanced and flexible crawling, indexing, retrieving and rendering features.
