ABSTRACT:
A data processing system is described including a host computer connected to peripherals by a Small Computer System Interface (SCSI) bus. A search processor is also attached to the SCSI bus and receives commands from the host as if it were a standard disc controller unit. The search processor responds to a write command to set up a search criterion, and then responds to a read command to perform a search, so as to retrieve data items satisfying the search criterion. If the logical unit number (LUN) in the command does not match the LUN assigned to the search processor, the command is passed transparently to the data store, allowing the host to access the data store directly.
