Abstract
Approaches for searching for key terms in a plurality of files include associating a respective key map with each file of the plurality of files in memory of a server. Each key map includes a plurality of bit values and each bit value indicates for a key term whether or not the key term is present in the associated file. The server inputs a search map, and the search map includes a plurality of bit values. Each bit value in the search map indicates for a key term whether or not the key term is a key term to search. The server determines for each key map, whether or not the key map satisfies the search map. Data indicating each file of the plurality of files having an associated key map that satisfies the search map is output by the server.
