Dynamic query system and method under concurrent query condition

Abstract

The invention discloses a dynamic query system and method under a concurrent query condition. The system comprises an index file disk, a buffer, an index file retrieval device, a request dispatcher and N query responders, wherein any one of the query responders is used for carrying out first search responding on a received query request by utilizing an inversion table stored in the buffer, returning a corresponding search document set back to a corresponding user terminal if the corresponding search document set is obtained after the first search responding , carrying out second search responding on the received query request by utilizing an inversion table stored in the index file disk if the corresponding search document set is not obtained after the first search responding, and returning a search document set obtained after the second search responding to the corresponding user terminal. According to the system and method disclosed in the invention, the aim of further decreasing the query response time is realized and then the query experience of the users is improved.

Description

technical field [0001] The invention relates to the technical field of information query, in particular to a dynamic query system and method under concurrent query conditions. Background technique [0002] With the rapid development of the current Internet, the amount of Internet information that people can access becomes more and more. In order to obtain the information they need from massive amounts of information, users need to use various Internet search engines to filter information. [0003] In the process of working, search engines often face query pressure brought by high concurrent query requests. In order to cope with the huge query pressure, mainstream search engines will use distributed clusters to share the user's query load. However, at present, when a single query response node responds to a query request, it usually obtains the corresponding query results directly by querying all the index files stored in the disk. The technical solution for performing que...

However, at present, when a single query response node responds to a query request, it usually obtains the corresponding query results directly by querying all the index files stored in the disk. The technical solution for performing query operations on the Internet consumes a large amount of query time, causing users to wait for a long time and reducing user experience
