description The invention relates to the field of semantic analysis, and particularly discloses an information retrieval method and device, equipment and a storage medium, the method comprises the following steps: obtaining a first character string, partially overturning the first character string, generating a second character string, and generating a character string set according to the first character string and the second character string; constructing an AC automaton according to the character string set; acquiring to-be-retrieved information input by a user, matching the to-be-retrieved information in the AC automaton, and acquiring a matching path of the to-be-retrieved information in the AC automaton; acquiring corresponding affix character strings according to the matching path, and permutation and combination of the affix character strings to obtain one or more affix character string combinations without character repetition; scoring the affix character string combination according to a preset scoring rule, an
