Abstract

The embodiment of the invention discloses a data searching method and device and electronic equipment. The method comprises the steps of obtaining a data set and determining a first index type corresponding to the data set; according to a BOHB algorithm, determining a first index construction parameter corresponding to the index type in a preset index construction parameter set; determining a first index search parameter corresponding to the first index construction parameter in a preset index search parameter set according to a BOHB algorithm; and outputting the first index search parameter. By means of the method, the better first index type, the first index construction parameter and the first index search parameter can be obtained through the BOHB algorithm, that is, the better index method and index parameter are obtained, the index performance can be improved, and then the use experience of a user is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data search method, device and electronic equipment. Background technique [0002] In a vector index database, for a given data set, different indexing methods and indexing parameters will have different indexing performance, such as recall rate, indexing speed, etc.; There are important influences. [0003] Methods for obtaining optimal index parameters in the prior art include grid search and Bayesian optimization, but the above two methods not only have their own shortcomings, but also cannot be used for vector index databases. [0004] Therefore, how to obtain a more suitable indexing method and indexing parameters in the case of a given data set, so as to improve indexing performance and user experience is a problem that needs to be solved at present. Contents of the invention [0005] In view of this, the embodiments of the present invention provide a data search me...
