Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds. Automated information retrieval systems are used to reduce what has been called information overload. An IR system is a software system that …

Information retrieval is, in general, an iterative search process, in which the user often has several interactions with a retrieval system for an information need. The   Information Retrieval (IR) is required to retrieve related documents to user's queries. IR is the process of finding data in the form of text by the required information  The process may then be iterated if the user wishes to refine the query.
