High speed search system

Claim 2

A high speed search system for operation in conjunction with a general purpose computer having a data storage device containing records in the form of digitized information and a data input/output terminal connected to it comprising: interface means for receiving queries and commands from said data input/output terminal and a portion of the digitized information from said data storage device; said interface means also transmitting search results to said data input/output terminal; a query processor; a symbol logic unit; buffer memory means for containing said portion of the digitized information from said interface means, and applying said portion to said symbol logic unit and said query processor; each of said records having zones identified therein; said query processor receiving (a) a query defining data to be located, and (b) all the digitized information from said buffer memory means; control and timing means for receiving said queries and commands from said interface means; said symbol logic unit receiving said digitized information from said buffer memory means, recognizing control character sequences and applying corresponding control signals to said query processor; and said query processor searching only that portion of said digitized information from said buffer memory means as is contained in the zones and records it has been directed to search, and providing search results to said interface means.

Claim 3

A high speed search system in accordance with claim 1 wherein: said query processor contains character logic means wherein the characters of its query are compared with the characters in the digitized information it has been directed to search.

Claim 4

A high speed search system in accordance with claim 1 wherein: said query processor contains field logic means for determining whether a matched term meets other requirements of a query.

Claim 5

A high speed search system in accordance with claim 1 wherein: said query processor contains a zone memory for containing one or more zone groups identifying zones of each record to be searched.

Claim 6

A high speed search system for operation in conjunction with a general purpose computer having a data storage device containing records in the form of digitized information and a data input/output terminal connected to it comprising: interface means for receiving queries and commands from said data input/output terminal and a portion of the digitized information from said data storage device; said interface means also transmitting search results to said data input/output terminal; a plurality of query processors; a symbol logic unit; buffer memory means for containing said portion of the digitized information from said interface means, and applying said portion to said symbol logic and said plurality of query processors; each of said records having zones identified therein and having a unique sequence number in said buffer memory; each of said query processors receiving (a) a query defining data to be located, and (b) all the digitized information from said buffer memory means; control and timing means for receiving said queries and commands from said interface means; said symbol logic unit receiving said digitized information from said buffer memory means, recognizing control character sequences and applying corresponding control signals to said query processors; and each of said query processors searching only that portion of said digitized information from said buffer memory means as is contained in the zones and records it has been directed to search, and providing search results to said interface means.

Claim 7

A high speed search system for operation in conjunction with a general purpose computer having a data storage device containing records in the form of digitized information and a data input/output terminal connected to it comprising: interface means for receiving queries and commands from said data input/output terminal and a portion of the digitized information from said data storage device; said interface means also transmitting search results to said data input/output terminal; a plurality of query processors; a symbol logic unit; buffer memory means for containing said portion of the digitized information from said interface means, and applying said portion to said symbol logic and said plurality of query processors; each of said records having zones identified therein and having a unique sequence number in said buffer memory; each of said query processors receiving (a) a query defining data to be located, and (b) all the digitized information from said buffer memory means; control and timing means for receiving said queries and commands from said interface means; said symbol logic unit receiving said digitized information from said buffer memory means, recognizing control character sequences and applying corresponding control signals to said query processors; and each of said query processors searching only that portion of said digitized information from said buffer memory means as is contained in the zones and records it has been directed to search, and providing search results to said interface means.

Claim 8

A high speed search system in accordance with claim 5 wherein: each of said query processors contains character logic means wherein the characters of its query are compared with the characters in the digitized information it has been directed to search.

Claim 9

A high speed search system in accordance with claim 5 wherein: each of said query processors contains field logic means for determining whether a matched term meets other requirements of a query.

Claim 10

A high speed search system in accordance with claim 5 wherein: a plurality of data input/output terminals are connected to said general purpose computer; and each of said data input/output terminals is capable of utilizing one or more query processors.

Claim 11

A high speed search system in accordance with claim 5 wherein: each of said query processors contains a zone memory for containing one or more zone groups identifying zones of each record to be searched.
