1. An information processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
perform a first collation process of collating first feature information extracted from a person included in a first image with first feature information indicating a feature of a region including a region other than a face of a retrieval target person to acquire a first collation result;
extract second feature information indicating a feature of a face from the person as a candidate included in the first image in a case where the first collation result indicates a match;
store the extracted second feature information of the candidate in association with the retrieval target person in a first storage unit;
perform a second collation process of collating the second feature information of the candidate with the second feature information stored in a second storage unit in association with identification information of a specific person to acquire a second collation result; and
in a case where the feature of the face is not extracted as the second feature information of the candidate, perform the second collation process using biological recognition information of the candidate with the second feature information stored in the second storage unit in association with the identification information of the specific person to acquire the second collation result; and
cause an output unit to output the identification information stored in the second storage unit in a case where the second collation result indicates a match, wherein
