Abstract: A data sort method, apparatus, and program to receive a character string of sort key items specified as keys of a data sort process, generate an automaton corresponding to a record whose final transition state corresponds to the character string, determine the order specified by the character string by scanning the automaton, and determine the order of the records corresponding to the character string.

Abstract: A full text search system using a character string collation method which searches a large quantity of data using a plurality of search processing apparatuses is disclosed. This system comprises a search integration unit which divides search-target character string data into a group of character string records, allocates the divided records to one or more search processing apparatuses, transmits given character string search conditions to each search processing apparatus, and receives and integrates search results. Furthermore, this System comprises an update temporary storage unit which temporarily stores new character string records to update the search-target character string data and an update record search instruction unit which instructs the new character string records stored in the update temporary memory unit to any one of the search processing apparatuses determined in advance as a part of the search-target character string data.
