limit | Number of counts to show, i.e., number of buckets. Optional. | List of facet fields separated by semicolons, e.g.: studies;type. For nested faceted fields use >>, e.g.: chromosome>>type;percentile(gerp) | query
Users can query multiple stats by separating field names by semicolons. E.g., chromosome[1,2];biotypes
Ranges
When asking for ranges, the result contains multiple buckets over a numeric field. You must specify the field name, the lower and upper bounds and the step or bucket size.
...
Nested facets allow users to nest bucketing terms, ranges or aggregations. In order to specify nested facets you must use the symbols: symbols >>
Some examples:
| chromosome>>typechromosome>>biotypes |
chromosome[1,2,3,4]>>type>>gerp>>biotypes>>gerp[0..5]:0.25 |
