Abstract: A portable electric energy storage system and a power regulation method thereof are provided. The portable electric energy storage system includes a housing, and an inverter and an energy storage battery disposed in the housing, and further includes: a power detector configured to detect a present power Pt of a connected load; a first comparator configured to compare the present power Pt with a rated power Pe of the inverter; a first actuator configured to regulate an output power of the inverter to a first preset power P1 if the present power Pt is greater than the rated power Pe of the inverter; and a second actuator configured to gradually regulate the output power of the inverter to a second preset power P2 after the connected load is driven to start operation or operate for a period of time; or determine whether to stop driving output of the load.

Abstract: Described are an application search method, apparatus, and terminal. In the method the terminal acquires a search word and converts the search word to a tag in a pre-constructed tag library, where the tag in the tag library corresponds to one category of applications. The terminal queries for applications corresponding to the tag and uses the applications as a search result corresponding to the search word. The apparatus may be implemented in the terminal and may include: an acquiring module, a conversion module, and a query module. In the present disclosure, a search word is converted to a tag in a pre-constructed tag library, and applications are searched for according to the tag.

Abstract: The present disclosure provides a method, server, system, and a storage medium for search term obtaining and recommendation. A tag library is set to include multiple tags, multiple categories, and multiple application keywords stored therein. When it is determined that a received application keyword is a fuzzy keyword, a tag matching the received application keyword is obtained according to the received application keyword. A category corresponding to the matching tag is obtained. Categories are obtained and gathered to find a category from the obtained categories that appears most frequently. A tag corresponding to the category that appears most frequently is found as a recommended search term. As such, when a user has an unclear subjective search purpose, a potential requirement of the user can be excavated, or a user's requirements can be refined, to allow a search result better matching user's intentions to thus improve practicability.
