The invention provides a search method and device, which relates to the field of computer technology, and solves the problem of low accuracy of the reference text of the specialized field determined by the existing technology. The method includes: acquiring n named entities (S300) in the current target case to be analyzed; determining the first and second features (S301); generating the target eigenvectors (S302) corresponding to the target case according to the preset rules of vector generation according to the first and second features; acquiring the feature vectors corresponding to each historical case and each historical case in the database (S303); The similarity between the target eigenvectors and the corresponding eigenvectors of each historical case is calculated, and the historical cases whose similarity results satisfy the presupposed conditions are selected as reference cases (S304).
