Zusammenfassung:A search term is received at deduplicated storage storing data segmented into segments. Segment fingerprints are generated and metadata maintained to allow reconstruction of the segmented data. The metadata includes fingerprint listings indicating sequences according to which the segments should be reconstructed. The segments are read to determine whether there are any matches of the search term. Matches are recorded in a results table. A first fingerprint listing associated with a first object is read. The results table is queried for fingerprints in the first fingerprint listing to determine whether the first object references any matches in the results table.
