Abstract: Embodiments of this application disclose a network device control method and apparatus. Specifically, a control apparatus may collect first working data, where the first working data includes a first measurement value, a first performance value, and a first device running parameter. The control apparatus determines whether the collected first working data meets a trend of a first set, where the trend of the first set is that an increasing/decreasing trend of measurement values in a plurality of groups of working data in the first set is consistent with or contrary to an increasing/decreasing trend of performance values in the plurality of groups of working data.

Abstract: A method and an apparatus for searching for a point of information. A client performs, based on a first search text entered by a user and first user data stored in the client, address extension on the first search text, to obtain a second search text that includes the first search text and includes first address information obtained based on the first user data. Because the first address information in the second search text is closely related to personal information of the user, it is highly probable that an address indicated by the first address information represents an address of a POI that the user expects to find. Therefore, it is highly probable that POI search results fed back by a server based on the second search text include a search result of the POI that the user is interested in or expects.

Abstract: A control method for performing a multi-table join operation and a corresponding apparatus are disclosed. Fields in a table whose fields participating in a theta join operation and used in the query statement meet a first preset condition are decomposed, to obtain a plurality of first field groups, so that the theta join operation can be implemented in steps in a form of the plurality of field groups. This can reduce a data amount of Cartesian product calculation during one join operation, greatly reduce network transmission overheads, computing overheads, and memory overheads, and improve execution efficiency.
