Abstract
An associative information retrieval system accepts information from a user and generates a query mask utilizing nested superimposed code words to search through and to find partial matches with the content of an auxiliary store. The auxiliary store contains similarly generated code words each produced from attribute values of records on a central store. The user information is put through the system on a character-by-character basis and the user is fed back information on the number of possible matches. The feedback informs the user on the incremental progress of the search produced in response to each newly entered character and also as part of a sequence that it may form with previously entered characters. The feedback information helps the user direct the search which the person does by supplying additional characters. When the number of possible matches is reduced to a manageable list, the index codes associated with the partially matching stored code words in the auxiliary store are used to locate complete records from a central store for display to the user to complete the retrieval process. In this latter process, false drops are eliminated by matching characters used to form the query mask directly with those of the records which were located via the nested superimposed code words.
