File name index generation method and device and file searching method and device

The invention provides a file name index generation method and device and a file searching method and device, and relates to the technical field of computers, in particular to the technical field of file searching and file indexing. According to the specific implementation scheme, a file name and a file identifier of a to-be-processed file are obtained; segmenting the file name according to a preset word segmentation rule to obtain at least one field in the file name; filtering the at least one field according to a preset filtering rule, and taking each field obtained after filtering as an index word; and generating a filename index of the to-be-processed file according to the index word and the file identifier. According to the method and the device, each field after word segmentation can be filtered when the filename index of the corresponding file is generated, so that the data volume of the generated filename index is reduced, and the file searching speed is increased. 本公开提供了一种文件名索引生成方法、装置、及文件查找方法、装置，涉及计算
