An approach for managing a set of data tuples is provided. A search tuple is received and a comparison relation is determined. The set of data tuples is ordered based on the comparison relation. A placement of the search tuple is determined between two consecutive data tuples in the ordered set of data tuples so that the search tuple is ordered among the ordered set of data tuples in accordance with the comparison relation. A presentation is generated based on the placement of the search tuple between the two consecutive data tuples. The presentation includes a sequence of data tuples included in the ordered set of data tuples. The sequence includes the two consecutive data tuples and the search tuple between the two consecutive data tuples.
