摘要： A computerized device, computer program product and method for performing a range search in numeric time-series data that includes a) acquiring, at least temporarily, a numeric time-series including a plurality of readings associated with time; b) processing, by a first processing unit, the acquired numeric time-series to derive an index from the acquired numeric time-series; c) storing the index in a storage unit; d) receiving a search request including an amplitude range criterion; e) processing, by a second processing unit, the index to determine a time range for which the numeric time-series is known to match the amplitude range criterion; and f) outputting the determined time range in response to the search request, whereby the processing time for determining the time range in response to the range search request may be significantly reduced.
