Abstract: The present disclosure provides a data prefetching method, a data prefetching apparatus, an electronic device and a computer-readable storage medium. The data prefetching method includes: acquiring a query prefix inputted by a user; analyzing the query prefix in accordance with a pre-trained linguistic model to acquire a perplexity of the query prefix; judging whether the perplexity is smaller than a predetermined threshold; and transmitting a prefetching request in accordance with the query prefix when the perplexity is smaller than the predetermined threshold.

Abstract: A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes an actuating screw and a stopper. The actuating screw is screwed into the stopper. While the actuating screw is rotated in response to a rotational force, the actuating screw is moved in a screwing manner, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by a first stopping part of the stopper, the keycap is switched from the pressable state to a non-pressable state.

Abstract: A mouse device includes a casing and plural key modules. The plural key modules are installed on two opposite sides of the casing. Each key module includes a switch, an elastic element, a keycap and a stopper. The switch and the elastic element are disposed within the casing. The keycap is detachably connected with the elastic element. The elastic element is arranged between the keycap and the switch. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved in a direction toward the switch and the elastic element is moved with the keycap, so that the switch is triggered by the elastic element. The stopper is detachably connected between the keycap and the elastic element. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.

Abstract: The present disclosure provides a data search method, and relates to the field of computer technology. The method includes determining semantic-understanding information corresponding to a received search term by subjecting the search term to semantic understanding; analyzing the semantic-understanding information to obtain timeliness requirement information of the search term; determining an acquisition mode of resource result corresponding to the search term based on the timeliness requirement information of the search term; and obtaining the resource result corresponding to the search term by using the determined acquisition mode. The present disclosure further provides a data search apparatus, a system, a device, and a computer readable storage medium.

Abstract: A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes a movable block, a push block and a stopper. While the movable block is pushed and moved in response to a pushing force, the push block is correspondingly moved. While the push block is moved, the stopper is pushed by the push block, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.

Abstract: The present disclosure provides a method of optimizing a search system, which relates to a field of data processing, and in particular to a field of data search. The method is implemented to include: determining a first hit rate of a cache unit of the search system for a plurality of user queries; for each element in a first set of elements, determining at least one key element by: generating a plurality of first queries that correspond to the plurality of user queries; determining a second hit rate of the offline cache unit for the plurality of first queries; and determining the element as one of at least one key element in response to determining that a difference between the second hit rate and the first hit rate is less than a difference threshold; and optimizing the search system based on the at least one key element.
