Abstract
The invention discloses a video file indexing method. The method comprises the following steps of: receiving a keyword sent by a client; taking a first coordinate information, which is determined by an identifier list and corresponding to the keyword, as an event coordinate; according to a video file list, inquiring all coordinate sequences comprising coordinate information in a preset range around the event coordinate used as a center; acquiring video label information corresponding to each coordinate sequence, wherein the video label information forms an undetermined query result list; and transmitting the undetermined query result list to the client. The invention also discloses a server. Through the identifier list and the video file list, the video label information indexed by the keyword can be screened, thus, the undetermined query result list meeting requirements of the client can be obtained quickly, the client can select the video label information according to the undetermined query result, and the needed video file can be obtained.
