SEARCH ENGINE SYSTEM BASED ON DISTRIBUTED DATA STORAGE DEVICE AND SEARCH METHOD THEREOF

摘要

The present invention relates to a search engine system based on a distributed data storage device and a search method thereof. According to an embodiment of the present invention, a search engine system based on a distributed data storage device comprises: a user terminal which can be connected to a network and inputs a search request; a search engine server which includes an index module for generating index data including an inverted index file and an original document file with respect to a target document when the target document for index generation is collected; and a distributed storage device for receiving and storing the original document file generated by the index module, wherein when the search request is input from the user terminal, the search engine server parses and analyzes a search query corresponding to the search request, calculates a search result for the search request by using an inverted index file including words included in the search query, and returns the calculated search result. According to an embodiment of the present invention, all the search engine nodes share only the inverted index file among index result files including the inverted index file and the original document file, and the original document file is stored in the distributed data storage device, thereby reducing costs for transmitting unnecessary data, and improving the search speed by allowing search to be performed through only the inverted index file when a search query request is performed.;COPYRIGHT KIPO 2020
