A symbol or number used to identify a particular value in a series of similar values.
A file created from the Full-Text File or other database to facilitate searching. Sometimes called an "inverted file," an index consists of all terms that are not Stopwords and are found in a given Field (if Fields exist in the file). In the initial step of creating an index, the terms are listed in the order of their occurrence in the Full-Text File. Then they are alphabetized ("inverted") and stored with the addresses of the text locations where they occurred. When the user enters a search request, the term(s) can be found quickly in the alphabetized listing. the associated addresses may be used for a further test such as Proximity and are then translated into the Set of Text Units that are the Hits of the search.]
