Abstract: This research investigates information retrieval from distributed databases. The most famous system for this work is the regular web search engines. Thus, this paper discusses in depth the search engines systems and have made an evaluation of different search engines based on popular queries searched. Before going into evaluation phase, we explore the structure of the search engines and explain its functions behind the scenes, how they can get the results for a specific query. The key idea behind search engines is the ranking algorithms used to bring the appropriate results. The paper chooses Google, Yahoo, and Bing to do evaluation experiments, since they are top search engines used in nowadays.
