Search Engine It is an information retrieval system designed to help search for information stored on any computer system.
The search results are usually displayed in the form of a list of where the information is located and arranged according to specific criteria.
Search engines allow to shorten the search duration and overcome the problem of escalating data volumes (flooding my information).
The search engine solves three issues:
- Compare the queries expressing the consultant's need with the information stored within the system.
- The consultant needs representation with a query that can be compared with the information stored within the system.
- Evaluating the results presented by the system and their response to the consultant's need.
The most popular search engines are those used on the World Wide Web called the search engines on the web.
How search engines work
Search engines provide an interface for a set of elements that enables users to define criteria about an element of interest and have the search engine find matching items.
Criteria are referred to as a search query.
In the case of text search engines, the search query is usually expressed as a set of words that defines the desired concept that one or more documents may contain.
There are many search query syntax patterns that differ in accuracy.
It can also switch names within search engines from previous sites.
While some text search engines require users to enter two or three words separated by a white space, other search engines may allow users to select documents, images, sounds, and various forms of the entire natural language.
Some search engines apply improvements to search queries to increase the possibility of providing a specific set of items through a process known as query expansion.
Understanding Query can be used as a language for query standardization.
