Citeseer: a search engine for scientific publications

It's name is Citeseer. It's an efficient dedicated search engine for the retrieval of scientific publications mainly focused on the topics of computer and information science. It's an excellent document retrieval system which allows to do queries in different ways (e.g. starting by the title of the paper, or by authors, citations etc). Very useful. Citeseer's main sponsor are the National Scientific Foundation, the Microsoft Reasearch Group and the NASA.

Simply because, in comparison with a "generic" search engine, this engines have less document to manage. And so the informational complexity is lower. More informations about Citeseer here.
