Abstract

A search device includes an accelerator and a CPU. The accelerator includes a plurality of search cores and a scheduler. The scheduler is configured to distribute target text to the search cores in units of records ordered by record sequence number, and the search cores are configured to perform automaton matching on the distributed records in a parallel fashion. The CPU is configured to construct an automaton in accordance with a search expression input thereto, and to perform logical expression evaluations in order of the record sequence number on matching results obtained on a record-by-record basis.
