Abstract
A search system that can easily search documents while ensuring the security is provided. A computer system includes one or a plurality of client devices, a search server, and a storage server connected to each other via a communication channel, and conducts search in response to a search request from one client device. The storage server stores a disk image that allows the client device to perform a boot operation via a network, thereby providing data search service to the client device.
Claims19
A computer system comprising:
- at least one client device;
- a search server;
- and
- a storage server,
- wherein the at least one client device, the search server, and the storage server are connected to each other via a communication channel so that search is conducted in response to a search request from one client device, and
- the storage server stores a disk image that allows the client device to perform a boot operation via a network, thereby providing a data search service to the client device.
A storage server forming, together with at least one client device and a search server, a computer system that provides a data search service to the at least one client device,
- wherein the storage server stores a disk image that allows the at least one client device to perform a boot operation via a network.
A search server forming, together with at least one client device and a storage server, a computer system that provides a data search service to the at least one client device,
- wherein the search server obtains data from a disk image stored in the storage server via a communication channel to form a search index.
A client device connected to a computer system comprising at least one client device, a search server, a boot server, and a storage server and providing a data search service,
- wherein the client device, which is not provided with a locally connected external storage mechanism, performs a boot operation via a network to obtain an area in which data is stored from the storage server.
A search method for conducting search in response to one of at least one client device in a computer system comprising the at least one client device, a search server, and a storage server connected to each other via a communication channel, the storage server storing a disk image that allows the client device to perform a boot operation via a network, the search method comprising:
- forming search index data from document data stored in the storage server;
- and
- verifying a search target against the search index data when conducting search.
