Abstract
Search servers, end devices, and search methods are provided. A search server includes a global index database and a processing unit. The processing unit executes a message queue service conforming to an asynchronous communication protocol. The message queue service receives a query comprising a keyword, determines that the global index database has no global search result corresponding to the keyword, distributes the keyword to a plurality of end devices in the distributed network, receives a plurality of local search results from at least a portion of the end devices, generates a global search result for the keyword according to the local search results, and stores the global search result in the global index database.
