Embodiment Construction

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0025] In the prior art, when querying a graph database, the sequence of query objects is irrelevant, resulting in a very large query volume, low efficiency and poor performance. For example, to find out Zhang San who stole in Hangzhou, if the order of querying graph data starts from the theft events in Hangzhou, then the actual query process is: find the thief whose location is Hangzhou from the index of theft events There are many theft events in Ha...

Abstract

The invention provides a data query method and device, electronic equipment and a storage medium, and the data query method comprises the steps: obtaining index information which comprises at least one query condition; determining the weight of each query condition; and determining a priority sequence of the query conditions based on the weight of each query condition, and performing search based on the priority sequence to obtain a query result matched with the index information. The method can reduce the query quantity, improve the query efficiency and improve the performance.

Description

technical field [0001] The present invention relates to the technical field of image search, and in particular, to a data query method, device, electronic device and storage medium. Background technique [0002] When querying a graph database, users usually only need to query a few related objects, and do not care about the order of query objects. However, in the query process of janusgraph (an open source distributed graph database), the order of query related objects is The order has a very important impact on query performance. If the selection of the sequence is unreasonable, the query volume will be very large, resulting in low efficiency and poor performance. SUMMARY OF THE INVENTION [0003] The present invention provides a data query method, device, electronic device and storage medium, which can reduce query volume, improve query efficiency and improve performance. [0004] In order to solve the above technical problem, the first technical solution provided by t...
