Embodiment Construction

[0021] The lucene-based index synchronization search method is particularly characterized in that it includes the following steps: first, an rsync server (rsync server) is deployed on an index server (Indexer server), and an rsync client is deployed on a search server. During this period, the version of rsync must be consistent.

[0022] After that, create an index locally through the index server, update the version file of the index to be consistent with the version file of the search server, and perform index synchronization. Specifically, the version file of the index will be updated. Once the search server detects the change of the version file on the index server, rsync will be used to synchronize the index to the local.

[0023] As far as a preferred embodiment of the present invention is concerned, after the index is synchronized, the index synchronization program tries to re-synchronize the index when it finds a problem with the index, and the search program on the se...

Abstract

The invention relates to a method and a device for synchronously searching indexes on the basis of a Lucene. The method is characterized by comprising deploying an rsync service side on an index server; deploying rsync client sides on search servers. Indexes are created by the index server locally, version files of the indexes are updated and are consistent with version files of the search servers, and the indexes are synchronized. The device comprises a search load balancing server. A main data communication side of the search load balancing server is connected with a user interaction assembly. An auxiliary communication side of the search load balancing server is connected with a data exchange hub assembly, the data exchange hub assembly is connected with an rsync server by a search server group, and a communication side of the rsync server is connected with an index assembly. The method and the device have the advantages that the problem of bottleneck of the index performance of a single server can be effectively solved, and the problem of influence of errors of the single server on index search implemented by a user is solved; the storage bottleneck of disks can be prevented by means of expanding the search servers.

Description

technical field [0001] The invention relates to a search method and a device thereof, in particular to a Lucene-based index synchronization search method and a device thereof. Background technique [0002] When the index is placed on a single server, if the performance of the single server is not good, it is usually considered to share the index with multiple servers to improve performance, but the disk performance of the server storing the index must be very strong, otherwise if the data volume continues to expand, it is easy to achieve The storage bottleneck of the disk, and if there is a problem with the server with the index, other servers will not be able to search. [0003] Regarding Lucene, it is a Java-based full-text information retrieval toolkit. It is not a complete search application, but a full-text retrieval engine architecture, which provides a complete query engine and index engine, and some text analysis engines (English and German) bilingual). Lucene is c...
