Currently, no help is provided when choosing an aggregate type. It makes it very difficult for someone to choose from the existing options.
- Add contextual help in aggregate editor / aggregate type field
- Histograms to apply automatic ranges depending on results (e.g. every 500 dollars, every month)
- Ranges to define your own set of options (e.g. past, future, between X and Y)
- Terms for text and vocabulary entries mapping
- Significant terms to return interesting or unusual occurrences of terms in a set
