Index, query, relevancy 

Modern search technologies are based on two processes: indexing of available information, query processing and a following output of results. Speaking of the former, any program (whether it’s a desktop search engine, a corporate information system, or an internet-search engine) creates its own search domain. That is, processes documents and forms their index (organized structure that contains information on processed data). Afterwards this created index will be used for in processing the query. What follows might not be at all simple technology-wise, but it doesn’t present any complexity to the average user. Then the program processes the query (by the keyword or phrase) and shows a list of documents that contain this key phrase. Since the information is stored in the structured index, the query processing takes much less time (up to hundred times faster) than if it was the straight search (the document selection is conducted not through file overlooking, but through analyzing the text data in the index).

The program shows a list of results in the order of relevancy (the level of correspondence to the query text). Different technologies, obviously, use different methods of search and relevancy determining (number of word inputs, usage frequency, the ratio of the query to the number of words in the document, the intervals between the words of the query phrase in the searched files, etc.). Based on those criteria the “weight” of the document is determinted, and depending on it the file takes a certain position in the list of results. When dealing with Internet search everything gets complicated, since a lot of other factors are to be considered (Page Rank Google is an example). But that’s the topic for a whole other article, so let’s not touch Internet
