The invention provides a search method and device, a distributed search system, a medium and a program product, and relates to the technical field of search. The method comprises the following steps: a search node receives at least one target keyword sent by a search engine node, and sends the at least one target keyword to other search nodes except the search node; and then each search node obtains a plurality of search results according to at least one target keyword, a plurality of index files stored in the search node and a plurality of index file copies which are stored in the search node and are in a working state, so a plurality of search results are obtained. When one index file is lost, the index file copy corresponding to the index file is in the working state, so a complete search result can be obtained, the accuracy of the search result is improved, and the stability of the distributed search system is greatly improved.
Description
technical field [0001] The present application relates to the technical field of search, and in particular to a search method, device, distributed search system, medium and program product. Background technique [0002] A search engine is a keyword sent by the user's terminal device, using a specific strategy to search out the search results corresponding to the keyword from the pre-acquired inverted index file (also called an index file), and return the search result to A retrieval technology for the user's terminal equipment. Before providing search services for users, search engines usually need to create index files in advance based on original data files and store the index files. [0003] In the prior art, after creating an index file based on the original data file, it is usually necessary to pre-store the index file in the disk, and when receiving a search request containing keywords sent by the user's terminal system, traverse the disk according to the search reque...
