Extracting Documents from Cross Distance Operator

Hi I used the Cross Distance Operator to compare to datasets. Afterwards i now know which two datasets are the most similar. Is there a possibility to extract the original data. for example if the 2nd and 3rd data is the most similar that i want to display those 2 datasets.

In my program i compare emails. so if i know that others are very similar to them i want to display the data.
