Embodiment Construction
[0081] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0082] With the development of Internet technology, more and more people pay attention to search technology. In the user's search request, a small number of search terms account for a considerable proportion of the search request, and most of the search terms occur very rarely individually, so the search engine stores the search results of the few search terms frequently queried by the user in the cache. It can handle the search requests of most users. Each c...

The embodiment of the invention provides a search cache updating method and device, which can be applied to the technical field of multimedia. The search cache updating method includes: extracting a first search word corresponding to information of a hot content while the hot content is updated, updating the first search word to a first database; querying a first pre-established database according to a search word in a search request while the search request is received, and determining if a second search word is acquired or not; querying a second pre-established database according to the second search word while the second search word is acquired and it is determined that the second search word is valid, and acquiring a cache of a first search result; determining if the cache of the first search result is valid or not, and using information in the cache of the first search result as a first search request result if so; and sending the search request to a search engine if not, acquiring a second search request result, and updating the second search request result to a second database. The search cache updating method and device can improve the update speed of hot contents.
Description
technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for updating a search buffer. Background technique [0002] With the continuous development of search, the continuous upgrading and updating of popular content, and the continuous increase of search volume, in order to improve the performance and stability of search services, search cache is an indispensable and important factor. The cache is a temporary file exchange area, a memory that can perform high-speed data exchange. It exchanges data with the CPU before the memory, so the speed is extremely fast. In order to speed up the response speed of user queries, the cache has almost become the standard configuration of search engines. The search engine will put the search results of some hot content keywords into the cache. When the keyword is searched again, the search results can be directly retrieved from the memory without re-retrieving and ranking from...
