Method for realizing K-V reverse retrieval based on index technology

The invention relates to a method for realizing K-V reverse retrieval based on an index technology, which comprises the following steps: constructing index serial numbers in one-to-one correspondencewith keywords in the same main body in a database; aimed at the condition that the keywords corresponding to different main bodies are completely the same, partially the same or completely different,establishing a main body global unique identification code uniquely corresponding to each index serial number corresponding to each keyword in the same main body; establishing an index relationship between the main body global unique identification code and the main body, and an index relationship between the main body global unique identification code and each keyword of the main body, i.e., enabling one main body to correspond to one main body global unique identification code; indexing through the main body global unique identification code, and retrieving a corresponding target main body and all keywords contained
