The invention relates to a search result utility analysis-based industrial product vertical search engine arranging technology. Q is a search entry; Di is the ith search result; when Q has M search results, i is greater than or equal to 0 and less than or equal to M. The vertical search engine arranging technology comprises the following steps: segmenting the search entry Q and the search result Di; carrying out result utility F calculation on the segmented search entry and the segmented search result Di; arranging all the search results according to the result utility F, wherein the results with high result utility F are ranked close to the front and the results with low result utility F are ranked close to the back. According to the technology, the result utility is calculated and the search results are ranked according to the result utility, so that the correlation degree of the search results is greatly improved and the user experience and the ranking correctness are improved.
