Abstract

The embodiment of the invention discloses a data search method and device, equipment and a storage medium. The data search method comprises the steps of obtaining an original data packet; pre-filtering a first keyword of an original data packet through a pre-processing device in a programmable logic device to obtain a target data packet, the pre-processing device comprising a hash operation module, a data packet splitting module, a random access memory and a filtering and rejecting module; and searching a second keyword for the target data packet, wherein the first keyword and the second keyword form the target keyword. By additionally arranging a preprocessing device in a programmable logic device, the technical scheme can utilize existing resources of the programmable logic device to achieve preprocessing of a part of keywords in the target keywords, and reduce the follow-up query workload, and when the original query bandwidth is increased, hardware equipment does not need to be upgraded, and the data query efficiency can be improved on the basis that the cost is saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of digital communication, and in particular to a data search method, device, device and storage medium. Background technique [0002] With the rapid development of the Internet industry, there are more and more data analysis needs based on various industries, and the requirements for the indicators of the analysis system are also getting higher and higher, and one of the core functions of this type of system is keyword search. [0003] In the prior art, for the query function module of keyword search, the general system architecture is composed of a fixed-function chip (Application Specific Integrated Circuit, ASIC) and an external query device. Once the system is upgraded, for example, the bandwidth flow of the query function module is exceeded, It is necessary to replace the ASIC or external query device, and change the hardware design, that is, the larger the query bandwidth, the...
