Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046]The present invention provides an index file creation synchronization method and a search system, first of all it is judged whether the business file to be indexed has changed. Based on the judgment result, only when the business file changes, the index is constructed for the business file. In this way, business files can be selectively indexed, that is, only changed business files can be indexed, which can greatly reduce the execution density of index construction work, and overcome the existing index construction schemes that occupy too many system resources. defect. In addition, the inde...

Abstract

Te invention relates to the search technology, and provides an index file creation synchronized method and a search system aiming at the disadvantages that the existing index construction program occupies more system resources; the index file creation synchronized method comprises the following steps: an index creation command is received, service identification is extracted, and a source service document is read under the corresponding source directory; when the source service document and a target service document are judged to be different, the target service document is updated according to the source service document; a source index file is generated for the updated target service document, and a target index file is updated according to the source index file; an index server leads the updated target index file to be copied to a local virtual directory of an index file storage directory, which is attached to a search server by SSHFS progress, so as to lead the target index file to be transferred to the index file storage directory. The invention further provides a search system; the index creation and synchronization efficiency can be effectively improved and the operating complexity is reduced.

Description

technical field [0001] The present invention relates to search technology, more specifically, to a method for creating and synchronizing index files and a search system. Background technique [0002] With the maturity of digital information storage technology, the full-text retrieval of information has been widely used. From Internet search engines to library book searches, the application of information full-text retrieval technology can be seen everywhere. [0003] In the face of a huge information database, in order to improve the efficiency of full-text retrieval, it is often necessary to index the information. Taking Internet search engines as an example, search engine companies must build indexes on a large amount of webpage data mined every day in order to ensure that tens of millions of webpage search requests can be quickly responded to every day. However, existing index construction methods often require a large amount of system resources, and for large databases...
