Distributed retrieval method and device

The invention discloses a distributed retrieval method and device. The distributed retrieval method comprises the following steps: obtaining an additional data set and more than two sub-data sets; wherein the data size of the additional data set is smaller than that of the to-be-retrieved data set, and the additional data set and the more than two sub-data sets are obtained based on the to-be-retrieved data set; based on a query request input by a user, respectively retrieving in the additional data set and the more than two sub-data sets to obtain a first retrieval result corresponding to the additional data set and a second retrieval result corresponding to each sub-data set; wherein the first retrieval result is obtained before the second retrieval result. According to the method, the retrieval accuracy and the retrieval response speed can be improved. 本发明公开了一种分布式检索方法及装置，其中分布式检索方法包括：获得附加数据集和两个以上的子数据集；其中附加数据集的数据量小于待检索数据集，且附加数据集和两个以上的子数据集均为基于待检索数据集获得的；基于用户输入的查询请求，分别在附加数据集和两个以上的子数据集中进行检索，获得附加数据集对应的第一检索结果，和每个子
