A search engine is an information retrieval software program that discovers, crawls, transforms and stores information for retrieval and presentation in response to user queries. Concurrent comparison of 64 stored strings with variable length was achieved in 50 ns for an input text stream of 10 million characters/s, permitting performance despite the presence of single character errors in the form of character codes.

The new procedures, that Bush anticipated facilitating information storage and retrieval would lead to the development of wholly new forms of encyclopedia. We believe that credibility and reputation … [10] It was developed in Stanford and was purchased for $6.5 billion by @Home. Within this article Vannevar urged scientists to work together to help build a body of knowledge for all mankind. Databases are indexed also from various sources. Another example would be the accessibility/rank of web pages containing information on Mohamed Morsi versus the very best attractions to visit in Cairo after simply entering ‘Egypt’ as a search term. Google’s Deep Web search strategy involves sending out a program to analyze the contents of every database it encounters. However, some search engines can also lead students to less-than-desirable websites or websites without any valid content. In 1987 an article was published detailing the development of a character string search engine (SSE) for rapid text retrieval on a double-metal 1.6-μm n-well CMOS solid-state circuit with 217,600 transistors lain out on a 8.62x12.76-mm die area. One of the elements that a search engine algorithm scans for is the frequency and location of keywords on a Web page. Online search technology is barely 20 … or Lycos. Jansen, B.
