Elasticsearch index-based join query methods, devices, storage media, and electronic equipment

Abstract

This application relates to an Elasticsearch index association query method, apparatus, storage medium, and electronic device. The method includes: obtaining a patent query statement for original patent data in Elasticsearch; querying at least one first patent data according to a first query part, determining a first hash value bitmap corresponding to the first patent data, and intersecting the first hash value bitmap with the original hash value bitmap of the original patent data to obtain an intersection hash value bitmap; determining a first patent identifier bitmap corresponding to the intersection hash value bitmap according to a preset patent identifier mapping table; querying at least one second patent data according to a second query part, determining a second patent identifier bitmap of the second patent data, and intersecting the first patent identifier bitmap with the second patent identifier bitmap to obtain a third patent identifier bitmap; and determining the user's collected patent data according to the third patent identifier bitmap. This application has the effect of improving the efficiency of users collecting patent data in batches.
