Search Engine Structure

Explains the workings of the information retrieval systems of the Internet.

This paper describes the process by which Internet search engines, such as “Google” and “Yahoo”, search and retrieve information requested by users. The paper explains that the process works on the basis of created indexes and then explains the four elements of the indexing system, which are known as a document processor, query processor, search and matching function, and ranking ability.
“The document processor comprises a preparing, processing and inputting function when a search is conducted (Liddy, 2001). Several functions are inherent in this process, including normalizing the document stream, breaking it into retrievable units, metatagging subdocument pieces, identifying indexable elements, etc. The first three functions are known as pre-processing, and the main aim is standardization of multiple formats.”
