Paolo Ferragina coauthored Opportunistic Data Structures with Applications by Paolo Ferragina and others, introducing a compressed text index associated with the FM-index. It supports searching without storing a separate uncompressed copy of the text. The construction connects the Burrows-Wheeler transform to string-searching algorithms, making the repeated structure used by data compression useful for queries as well.[ref]
