Maps from the result ranking within a group to the overall (ungrouped) result ranking. For example, the highest ranking result in group 2 might be the 4th-ranked result overall. In this case, GetRank(2,0) would return 3 (note ranking is zero-based). Note that methods like GetFields() index results by the ungrouped ranking, so if you are presenting results by group this will probably be the first method you call for each result row.
