Embodiment Construction

[0018] Sphinx is a SQL-based full-text search engine that can be combined with MySQL and PostgreSQL for full-text search. It can provide more professional search functions than the database itself, making it easier for applications to implement specialized full-text search. Sphinx specially designs search API interfaces for some scripting languages, such as PHP, Python, Perl, Ruby, etc., and also designs a storage engine plug-in for MySQL.

[0019] A single Sphinx index can contain a maximum of 100 million records, and the query speed is 0.x seconds (millisecond level) in the case of 10 million records. The speed at which Sphinx creates an index is: it only takes 3 to 4 minutes to create an index with 1 million records, and it can be completed within 50 minutes to create an index with 10 million records. An incremental index that only contains the latest 100,000 records needs to be rebuilt once. It only takes tens of seconds.

Abstract

The invention provides a license number search method including the steps of A, adding location information of keywords of license numbers to each license number keyword index built by the Sphinx technique, B, receiving the license number search information input by users, C, building search conditions containing the license number keywords and locations of the keywords in the license numbers according to the search information input by the users, and searching in the license number keyword index according to the search conditions so as to determine search results. By the search technique, the search results can be more accurate while the search time is shorter.

Description

technical field [0001] The invention relates to the retrieval field, in particular to a method and device for license plate retrieval. Background technique [0002] According to the standard "Technical Standard-T669.9: Technical Requirements for Bayonet Information Identification, Comparison, and Detection System" published by the Ministry of Public Security, the vehicle information query response time has the following requirements: [0003] a) Accurate query: query the data with certain conditions in the database, and the query response time should not be greater than 3s; b) Fuzzy query: query the data with uncertain conditions in the database, and the query response time should not be greater than 6s. [0004] In a medium or large bayonet system, the number of license plate information in a year often reaches hundreds of millions or even billions. Fuzzy query of license plate information among hundreds of millions or even billions of pieces of information, the existing r...
