With the advent of computers, it became possible to store large amounts of information; and finding useful information from such collections became a necessity. The field of Information Retrieval (IR) was born in the 1950s out of this necessity. Over the last forty years, the field has matured considerably. Several IR systems are used on an everyday basis by a wide variety of users. Information retrieval is become a important research area in the field of computer science. Information retrieval (IR) is generally concerned with the searching and retrieving of knowledge-based information from database. In this paper, we represent the various models and techniques for information retrieval. In this Review paper we are describing different indexing methods for reducing search space and different searching techniques for retrieving a information. We are also providing the overview of traditional IR models.

Information retrieval is concerned with the organization and retrieval of information from large database collections [2]. Information Retrieval (IR) is the process by which a collection of data .
