WebFeb 6, 2024 · By default Faiss assigns a sequential id to vectors added to the indexes. This page explains how to change this to arbitrary ids. Some Index classes implement a add_with_ids method, where 64-bit vector ids can be provided in addition to the the vectors. At search time, the class will return the stored ids rather than the sequential vector ids.
