We introduce a scheme to address the trade-off between the identification rate, search and memory complexities in large-scale identification systems. We use a special database organization by assigning database entries to a set of possibly overlapping clusters. The clusters are generated based on statistics of both database entries and queries. The decoding procedure is accomplished in two stages. First, a list of clusters related to the query is detected. Then, refinement checks are performed on members of the detected clusters to produce a unique index. We investigate the minimum achievable search complexity for binary symmetric sources.
