Abstract

The invention provides a fuzzy retrieval method based on a hybrid cloud, and the hybrid cloud comprises a public cloud server and a private cloud server. According to the method and the device, the mixed cloud comprising the public cloud server and the private cloud server is utilized, the better computing capability and storage capability of the public cloud server and the better privacy and stability of the private cloud server are integrated, the alternative keywords are filtered and then verified, so that the more accurate fuzzy word set is obtained; and misjudgment and missed judgment are effectively reduced; meanwhile, the retrieved files are regularly sorted, so that the retrieved files can better meet the requirements of users.

Description

technical field [0001] The disclosure relates to the technical field of cloud computing and security information retrieval, in particular to a hybrid cloud-based fuzzy retrieval method. Background technique [0002] Fuzzy searches refer to searches that can tolerate misspellings and inconsistent formats. That is, when the user enters the search term, such as an English word, one or more characters may be misspelled due to memory errors or pressing the wrong keyboard. At this time, there will be no corresponding entry that matches the user's search, so the user cannot obtain desired result. Similarly, the user may not get the desired retrieval result because the input query word is not consistent with the format of the word in the entry (such as the input word is a noun and the entry word is a verb). Using fuzzy search can correct misspelled search terms, find some candidate keywords that users may really want to input, and return the corresponding search results. Fuzzy wo...
