People use search engines to find information they desire with the aim that their information needs will be met. Information
retrieval (IR) is a field that is concerned primarily with the searching and retrieving of information in the documents and also
searching the search engine, online databases, and Internet. Genetic algorithms (GAs) are robust, efficient, and optimizated
methods in a wide area of search problems motivated by Darwin’s principles of natural selection and survival of the fittest. This
paper describes information retrieval systems (IRS) components. This paper looks at how GAs can be applied in the field of IR and
specifically the relevance of genetic algorithms to internet web search. Finally, from the proposals surveyed it turns out that GA is
applied to diverse problem fields of internet web search.
