Index usage is categorized into buckets of different ranges. Each bucket has a range of values for access count and rows returned. An entry is placed into a bucket if the rows returned or access counts falls within the range of that bucket. DBA_INDEX_USAGE: DBA_INDEX_USAGE displays cumulative statistics for each index.
