The article discusses in detail the rich and complex network of related concepts. It presents the concept- and terminology-related issues of internet search engines; it highlights the relationships between concepts and synonyms. Further, it reviews related research areas, mentioning the invisible/deep web, data mining, and text mining etc., among others.
