Abstract: A single search system that returns relevant search results for a user search query by identifying user intent and context implied therein. The inventive system supports POI and address searches initiated from a single search box only. Search query data is input in to a single search box on a single search client to initiate a search for an arbitrary piece of data. Meta-data concerning a nature of a search is not provided to the single search system. A search servlet on a single search server uses an ordered series of filter methods to progressively extract specific aspects of user intent from a freeform search query, and accumulate intent information within a context shared by all filters. The single search system determines a data corpus to search based on context provided in a user search query. Relevant search results are returned to the single search client in a search response.

Abstract: A method of processing an external service request in a storage area network (SAN) is used for responding a service request in the SAN with multiple controllers, and the method includes the following steps. A first controller of the SAN receives a request packet of an external network. When the first controller determines that the request packet must be transmitted to a second controller actually providing service in an internal network, the request packet is transmitted to the second controller. The second controller receives the request packet, and parses a source address contained therein for recording. The second controller executes an operation instruction corresponding to the request packet, and then generates an acknowledge packet. The second controller takes the source address as a destination address of the acknowledge packet and directly transmits the acknowledge packet to an original request initiator.
