Abstract: A novel signature approach is introduced for
        retrieval of documents from large text databases.
        The structure of the signature files under this
        approach lends itself to a highly parallel hardware
        implementation. The signature files are generated by
        software and loaded into RAM. Upon a user query, the
        signature files are searched in parallel by a
        special-purpose search module for identification of
        relevant documents. The search module is implemented
        in hardware with a parallel architecture.
        Experimental results and the design of the search
        module are presented. Experiments have shown that
        this technique is quite efficient in terms of
        storage overhead and the number of false drops.
        Perhaps the most attractive feature of this system
        is the hardware cost. The signature files are
        designed so that they can be saved, accessed, and
        compared using inexpensive memory chips. Another
        feature of this system is the capability for simple
        manipulation of the 'don't care characters,' which
        is not provided by other signature methods
