The method includes: pre-processing, for each inverted list, constructing a two-dimensional scatter diagram by taking the index of the docID as the horizontal ordinate and the value thereof as the vertical ordinate, generating a linear regression straight line based on the least square method to get the minimum sum of squares of the vertical deviation from all the points in the diagram to the straight line, deriving a left secure search distance and a right secure search distance, and saving the derived linear regression information. The inverted index intersection determines the secure search range of the docID to be found in the inverted list according to the saved linear regression information about the inverted list, then applies a certain existing search method to search within the range. The inverted index intersection method of the present invention can narrow the search range, decrease the search time, shorten the response time of the search ...
