Abstract
An apparatus including a processor to index data records within a data cell, wherein for each data record, the processor retrieves data values from first and second data fields; determines whether the first and second data fields store unique data values; in response to the first data field storing a unique data value, adds an identifier of the data record to a first unique values index, in response to the second data field storing a unique data value, adds the identifier to a second unique values index, wherein identifiers of data records within the unique values indexes are ordered based on corresponding unique data values; and generates an indication of ranges of data values of the first and second data fields to enable a determination of whether a data value specified in search criteria is present within at least the data cell.
