Due to the low accuracy in current general search engines,and the poor search effectiveness of lower logistics in major domestic ports,the paper designs a port logistics Nutch-based vertical search engine system which achieves fast query and logistics information sharing.The system uses a theme based on vector space model identification algorithm and the relevance of the algorithm is improved by adding identification mechanism and the importance of metadata tags that contain the keywords of the weighting.Adding "tunnel handling" mechanism to deal with separation issues topic page,and modify the source code to sort search results to make it more responsive to the requirements of vertical search engines.
