2.1 Introducing Key-Objects. The structured search paradigm based on key-objects proceeds from analogy between the structured search and the keyword search where key-objects play the role of keywords, hence the name. As we know, keywords allow posing queries independently of indexed documents or web pages, that is, without knowledge of
