Embodiment 1

[0024] According to an embodiment of the present invention, an embodiment of a data query method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] figure 1 is a flowchart of a data query method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0026] Step S102, after obtaining the request sent by the user for querying the data to be queried, querying the target index block in the index body, wherein the target index block is the index block corresponding to the data to be queried in the index body , the index body includes a plurality of index layers, each index layer includes a pl...

Embodiment 2

[0069] The embodiment of the present invention also provides a data query device, the data query device is mainly used to execute the data query method provided in the above content of the embodiment of the present invention, the data query device provided by the embodiment of the present invention will be described in detail below.

[0070] Figure 4 is a schematic diagram of a data query device according to an embodiment of the present invention, such as Figure 4 As shown, the data query device mainly includes a query unit 10, a judgment unit 20 and an access unit 30, wherein:

[0071] The query unit 10 is configured to query the target index block in the index body after obtaining the request sent by the user for querying the data to be queried, wherein the target index block corresponds to the data to be queried in the index body An index block, the index body includes multiple index layers, each index layer includes multiple index blocks, and any two index layers are as...

Abstract

The invention provides a data query method and device, and relates to the technical field of data query. The data query method includes the steps of querying a target index block in an index body after a request sent by a user for querying to-be-queried data is obtained; determining whether or not the query condition is satisfied based on the data information corresponding to the target index block; if it is determined that the query condition is not satisfied, accessing the next-level index block corresponding to the target index block based on index subsequent identifiers, and determining whether or not the to-be-queried data is returned back to the user based on the data information corresponding to the next-level index block; the to-be-queried data is a document result mapped to the next-level index block in a data mapping table, the technical problem of low query efficiency of an existing data query mode is solved, and the technical effect of conducting fast and efficient data sorting query is achieved.

Description

technical field [0001] The present invention relates to the technical field of data query, in particular to a data query method and device. Background technique [0002] Today's data management systems, in order to meet business needs, often encounter the need for data sorting and querying. The common practice is to sort all the data, and then obtain the required data sets in order. This can meet business needs, but the efficiency is low , processing a lot of data that does not need to be accessed. Contents of the invention [0003] In view of this, the object of the present invention is to provide a data query method and device, so as to alleviate the technical problem of low query efficiency of the existing data query methods. [0004] In the first aspect, the embodiment of the present invention provides a data query method, including: after obtaining the request sent by the user for querying the data to be queried, querying the target index block in the index body, whe...
