A data search method and device

Abstract

The embodiment of the invention discloses a data searching method and device. The method comprises the steps that the query per second is calculated by a target server receiving search requests; when the query per second is smaller than an upper threshold value of the query per second, the target server searches for target data meeting the preset requirements in a local database; when the target data is found, the target data is returned to a target client; when the target data is not found, a second server cluster is made to search for the target data in a local cluster database; the second server cluster feeds the found target data back to the target server, and then the target data is returned back to the target client; under the situation that the second server cluster does not find the target data, and the query per second is smaller than a lower threshold value of the query per second, a third server cluster searches for the target data in the local cluster database, and the target data is fed back to the target server; the target server returns the target data to the target client. By means of the data searching method and device, the stability and effectiveness of search service can be improved.

Description

technical field [0001] The invention relates to the technical field of Internet applications, in particular to a data search method and device. Background technique [0002] In the era of Internet technology, operators provide users with search services through the search service system. Users can search for interesting data through the search service system. With the continuous increase of user needs, the search volume is also increasing. After receiving the user's search data request, the search service system searches the global search service system for the data to be searched according to a certain strategy. After searching for the corresponding data, it will feed back the searched data to the customer who uses end, so as to realize the search of data. [0003] There are many problems in the actual use of the above search method. If the query rate per second of the search request is too high, it will cause an unbearable pressure on the search service system, which in t...

Problems solved by technology

[0003] There are many problems in the specific use of the above search method. If the query rate per second of the search request is too high, it will cause an unbearable pressure on the search service system, which will cause a large number of timeouts for the search service. In the prior art, By setting the total query rate threshold per second, after receiving the search request, if the query rate per second is greater than the query rate per second threshold, the search request is directly rejected to ease the search pressure on the search service system

However, this method will prevent many search requests from being served, resulting in poor stability and effectiveness of the search service
