A method for reducing search complexity based on a specific strategy to cope with an overload search request

Abstract

The invention discloses a method for reducing search complexity based on a specific strategy to cope with an overload search request, which is characterized in that the method comprises the followingsteps of: 1, identifying a search request; 2, distinguishing a request from an additional processing policy flag; 3, processing the request by strategy; 4, returning a result; 5, periodically monitoring the dynamic adjustment strategy; 6: recording the process to assess the impact. The invention achieves the effect of controlling the range of the damaged service under the minimum influence degreeand making the searching complexity reduced to the dynamic adjustment according to the concurrent load condition of the searching request.

Description

technical field [0001] The invention relates to the technical field of data search, in particular to a method for reducing search complexity based on a specific strategy to cope with overloaded search requests; Background technique [0002] The search system is a high-load computing system that takes up a lot of CPU computing time and memory resources. At the same time, the online search system needs to maintain high availability, and the response time is required to be at the millisecond level. Therefore, the system resources it occupies and the amount it can handle The maximum concurrency of search requests must be proportional to a certain range; [0003] The operation of the company needs to consider economic benefits, and the hardware cost is limited; for the search platform, it belongs to the background service provider in the entire business system, which is open to all connected business systems, and the total processing capacity it undertakes It is relatively limit...

Problems solved by technology

[0003] The operation of the company needs to consider economic benefits, and the hardware cost is limited; for the search platform, it belongs to the background service provider in the entire business system, which is open to all connected business systems, and the total processing capacity it undertakes It is relatively limited; when there is an overloaded search request, that is, when the number of concurrent search requests exceeds the maximum load of the system, the search platform will easily overflow the instance memory or the load is too high, causing the application to crash and cannot provide services; Under the circumstances, it can cope with the occurrence of such overloaded search requests; the search platform system needs to have a specific strategy to reduce the complexity of the search, and realize the response to overloaded requests through the idea of ​​​​destructive services;
