As the saying goes,"hunger breeds disconte ntme nt", catering industry is one ofthe few less affected by economic cycles of the industry in recent years, with the rapiddevelopme nt of market economy, China’s catering industry has been rapiddevelopme nt, but the industry has the overall technology content low, the degree ofinformation is not e nough i n the developme nt process. With the rapid popularizationof Internet technology, people need high performa nce, high quality networkreservation infor mation service, a food web services provide convenient for the user,on the other ha nd extends the traditional catering business scope. In the onlineordering syste m, intellige nt search algorithm is a key link in the whole syste mrealization.The main contents of this paper are as follows:(1)The syste m introduced the network reservation s ystem background, dome sticand foreign developme nt present situation, the existing network ordering syste mdefects as well as the research purpose and meaning, analyzes the basic structure ofnetwork ordering syste m, the related concepts and the basic process, the searchalgorithm especially depth-first search, breadth-first search, HITS algorithm a ndPageRank algorithm are analyzed in detail.(2)Introduces the basic design thought of intellige nt search algorithm, designs agenetic ter m freque ncy inverse docume nt frequenc y intellige nt search algorithmGTFIDF. Ke yword weight strategy of ge netic algorithm a nd TF-IDF algorithmcombined with the algorithm, and detailed imple mentation steps and GTFIDFalgorithm impleme ntation process selection operation, crossover operation, mutationoperation, and the n GTFIDF algorithm a nd HITS algorithm, Pa geRank algorithm forthe performa nce test comparison. The experime ntal results show that GTFIDFalgorithm at run time, recall, precision rate is better than HITS algorithm a ndPageRank algorithm, which can be applied to the online ordering system.(3)Combined with the GTFIDF algorithm and the existing network reservationbusiness process, the design and i mpleme ntation of a network reservation s yste mbased on intelligent searching algorithms, introduces the syste m design principle,system function de mand, syste m data flow and the main E-R model in detail, analyzesand describes the structure design of the database of the system. At the same ti me, the main modules of the syste m such as ordering ma na ge ment, banquet reservationmanagement, food Raiders and order management, with examples in detail.(4) The full paper of the main conte nts and innovative work are summarized,analyzed the problems existing in the research process of this paper, and puts forw ardthe direction of further research.
