A standard approach to retrieving information from orderly database depends on word to word match between user request and that of the words assigned to documents in database. Because of diversity of words, stated methods of information retrieval are necessarily incomplete and imprecise. When large amount of data are to be handled, the use of information retrieval is concerned with the searching and retrieving of knowledge-based information from database. In this paper, the authors present a brief survey of information retrieval models and techniques in which searching on non-standardized huge document is highly difficult, where in indexing reduces the complexity of search process.
