Abstract
Paper presented at the IIS text retrieval and in-house systems conference, London, 6.-7.11.91. Traditionally, information retrieval has provided a well-defined area of activity approaches via a limited number of routes. It was primarily concerned with retrieving documents identified by sets of keywords (or key phrases). Some flexibility eas added by using Boolean combinations of the index terms. Currently, all these limitations are being trancended. For example, although full text retrieval is basically concerned with key words, it expands the meaning of keywords until they include virtually all the words in the text
