A special Applied Phlebotinum used primarily in Police Procedural dramas. No matter what sort of clue the Crime Scene lab has found (blood, wire, rope, oil, perfume, etc), somebody has manufactured a database designed to search through them all. Not only that, our heroes at the crime lab have purchased a copy of this software, the interface devices to input the data in question and have acquired the expertise to use this software (which has so far never been used in another one of their cases) with 100% accuracy on the first attempt. See Akashic Records for a related but older trope.
