    Abstract
    Considers 'about' as it is used in an information retrieval sense, e.g. when an indexer judges that a document is or is not about a given subject. An operational definition of 'about' is given in which it is interpreted in terms of search behaviour. Concludes that 'about' is not the central concept in document retrieval theory. A document retrieval system should provide a search output in which documents are ranked according to the probability that they will satisfy the user's information need rather that according to the degree that they are 'about' the topic. 'Aboutness' is related to satisfaction probability

    Abstract
    For many years it has been believed that in order to design optimal document retrieval systems one must assign index terms to documents at their optimal depth: therefore, it was of primary importance to answer the following question: "What is the optimal depth of indexing?" This article offers an analysis and answer to this question. We show that the issue of depth of indexing is, in fact, not a central issue in the design of effective document retrieval systems. It turns out that the answer to the question about optimal depth is a logical consequence of answers (which this article provides) to more fundamental questions about indexing and retrieval
