Abstract
In the literature and discussion about information retrieval (IR) the words "string", "word", "term" and "concept" are used inconsistently. There is no common agreement on the concepts named by these words. Thus the communication in IR is inefficient, inaccurate and prone to errors. Based on the concept of term in the study of terminology and on a three level model of IR, the paper seeks to clarify the terminology and proposes the terms string, search key and concept , with their subterms, for IR. Consequently it is proposed that a number of other words commonly used, such as "controlled term", "uncontrolled term", "free term", should not be used in IR.
