1. A computer related database lookup system embodied on a computer-readable storage medium, comprising:

  • a quantizer that forms a quantized vector having M components, M being an integer, the M components of the quantized vector having at least one of three values (0, 1, and q), wherein the quantizer assigns a value q to at least one of the M components;

    a threshold function T(x) processing the quantized vector to control at least one of a backtrack, lookup accuracy, lookup load balancing between systems, or noise margins;

    a component that performs the lookup in a database in accordance with the values, where q directs the component to perform the backtrack during the lookup, when encountered; and

    one or more controls to adjust the threshold function T(x).
