s401: and receiving a search instruction for instructing to search the video to be searched on the currently displayed online page.
In this embodiment, when a user uses a terminal, the user wants to search or find a video of an online page currently displayed by the terminal, and sends a search instruction to the terminal, and after receiving the search instruction, the terminal searches for the video on the online page currently displayed, where the video is a video to be searched, and the online page refers to a page that can be accessed to the internet, displays hyperlinks connected to other websites, or can be connected to a server, for example, a microblog, a wechat, or a browser page. It should be noted that, a user may issue a search instruction to a terminal in various ways, such as touch issuing, remote control issuing, voice control issuing, and the like, and may also issue a search instruction to a flexible screen or a curved screen terminal through a folding and bending display screen. The touch issuing may be an operation gesture directly performed on the display screen, the operation gesture may be a single operation or a preset combined operation, when only one operation is performed within a preset time interval, the operation is also the single operation in the embodiment, generally, the preset time interval is relatively short, the single operation may include a sliding operation or a clicking operation, and the like, and the combined operation in the embodiment is formed by combining at least two single operations, such as a continuous clicking operation, a clicking and sliding operation, and the like; for example, the long press operation is directly executed on the display screen, and the terminal recognizes the long press operation and receives the search instruction. The remote control issuing can be realized by remotely controlling the terminal through an infrared sensor, for example, when the terminal is an intelligent television, a search instruction is issued through a search button of a remote controller, and the terminal receives an infrared signal to search for a video to be searched. The voice-controlled issuing may be receiving, by a microphone, a voice issued by a user, and then identifying and judging whether the voice is a search instruction, for example, a voice keyword corresponding to the search instruction is a word such as "search", and the like, and of course, the voice keyword may be set by the user in a self-defined manner, or may be intelligently recommended or set by the terminal. The control issuing may be that a search control, such as a shortcut interface, a search button, and the like, is provided on an online page currently displayed by the terminal, and a user directly operates the shortcut interface and the search button, for example, after clicking the search button, the terminal searches for a video to be searched.
