A point of use water purification unit for continuously and completely purifying water at all point of use for removing all chemicals, killing all microorganisms; the device having a computer monitored and controlled system for degassing, super heating and exploding water into a vacuum chamber, condensing the steam in a counter current cold brine apparatus and stored in a holding tank. The support platform is in turn supported by a plurality of horizontally arrayed leaf springs. The plurality of first-segment members and second-segment members cooperate to form a substantially liquid-tight periphery when the driving member is in the extending position. The query manager utilizes the thread configuration data to conduct selective searches of the EMT volume. The combination includes identifying like commands each being associated with a file stored on a drive and ascertaining which of the files associated with the like commands are contiguous.
