Problems solved by technology

This kind of search is not only complicated, but also has high search efficiency only when the amount of data is very small. Obviously, traditional database search cannot satisfy the search of large data volume and arbitrary field combination.

Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] The middle layer system and information retrieval method for database information retrieval described in the present invention are mainly used in video websites to provide users with massive video information retrieval services, or in occasions with similar retrieval requirements, when users retrieve (query) through the application layer ) video information in the data table, an http address is given as a request and sent to the middle layer, and the middle layer parses the http address to obtain the relevant information retrieved by the request, completes the retrieval of the video information in the database, and sends the retrieval results Return work to the application layer.

[0050] The present invention is not limited to the video information retrieval service, and the structure of the middle layer system provided by the present invention can be...

Abstract

The invention relates to an interlayer system used for searching database information and an information searching method. The interlayer system comprises an API (Application Program Interface) application server group used for receiving a searching request sent by an application layer, wherein the API application server group is used for acquiring an ID of a searched video from an index server and acquiring the video from an on-line database according to the ID of the video. After the information of the on-line database is synchronized by an off-line database, an index is created and stored in an index server group by an index creating server. In the interlayer system used for searching the database information and the information searching method provided by the invention, the interlayer system can be used for receiving the searching request based on an http protocol, and after syntax analysis and engine analysis are performed, the data can be accurately acquired. The searching for the combination of any field with a large data volume is achieved, the searching time of the database is short, a data layer is separated from the application layer, and the development of the data layer and the application layer are free from being influenced by each other.

Description

technical field [0001] The invention relates to the technical field of online database retrieval or online search engine, in particular to an intermediate layer system and information retrieval method for database information retrieval. The database especially refers to a database used by video websites to store online video information. Background technique [0002] Existing video websites will provide users with video information retrieval services. Video websites classify video information and store them in databases. Video websites use many databases and data tables to store data. A database includes several data tables. Video information is stored in data tables. The traditional method of video information retrieval is: the application layer needs to fetch data from different databases and different data tables according to business requirements. The query of these data tables generally cannot achieve the high efficiency of using any query, and these Data tables may b...
