## Timeseries
The API supports `count` on date fields, which produces a timeseries at the granularity of **day**. The API returns a complete timeseries.

**Example query**
### Counting by date, returning a timeseries
This query looks in the `drug/event` endpoint for all records. It then returns a count of records per day, according to a certain date field (the receipt date of the adverse event report).
1. Search for all records
2. Count the number of records per day, according to the field `receiptdate`
