A video search method comprising:

• receiving search information;
• determining at least one video collection matching the search information;
• wherein the video collection comprises a first video, and a second video corresponding to the first video, the first video being a reply video generated by an object according to commentary content under any main video;
• the second video comprising the main video, or a video of same category as the first video, or both the main video and the video of same category as the first video;
• generating preview information corresponding to the video collection according to the first video, or according to the second video, or according to both the first video and the second video;
• displaying the preview information on a search result page, and displaying the video collection according to the preview information,
• wherein the determining the at least one video collection matching the search information comprises:
• obtaining a matched first video according to the search information;
• acquiring the second video according to key information and the search information in the first video, wherein the key information is a video theme in the first video or a key field in video content.

A server comprising a processor, a communication interface, a memory and a communication bus, wherein the processor, the communication interface and the memory communicate with each other through the communication bus;

• the memory is configured for storing a computer program;
• the processor is configured for executing the program stored in the memory to implement steps of a video search method, wherein the method comprises:
• acquiring search information;
• parsing the search information to acquire at least one field;
• in response to determining that there is a first video in a pre-built database that matches the search information according to the at least one field, acquiring the first video;
• in response to that a second video having an association with the search information is screened out from the database according to the first video, taking the first video and the second video as a search result and sending it to a terminal device, wherein the first video is a reply video which is generated by an object according to commentary content under any main video, and the second video comprises the main video, or a video of same category as the first video, or both the main video and the video of same category as the first video,
• wherein screening out the second video having the association with the search information from the database according to the first video comprises:
• acquiring key information corresponding to the first video according to the first video;
• extracting at least one video corresponding to the key information from the database according to the key information;
• and
• screening out the second video having the association with the search information from the at least one video.
