Summary:The invention provides a search method, which belongs to the technical field of search and is used for solving the problem that accurate search results cannot be obtained for information with multipletext index domains in the prior art. The method comprises the steps of determining at least one first search policy matched with a query text, wherein each first search policy corresponds to at leastone text index domain and a search weight matched with the text index domain; based on each first search policy, executing search operation of the query text in each corresponding text index domain;and performing merging output on search results of all search operations. Through the method disclosed by the invention, the mistaken recall in literal hitting of unrelated text index domains is avoided, and the result correlation is effectively improved; and by matching corresponding search weights for different text domain indexes, the ranking of the search results is optimized, and the accuracyof the search results is ef
