@ -84,9 +84,22 @@ All operators can have a trailing `?` to make them consider fields without
value as matching the condition as well. This means you can use something like
```
> /api/v1/reports?filter[expiration_datetime][gt?]=2018-10-18T09:06:38.538375
> GET /api/v1/reports?filter[expiration_datetime][gt?]=2018-10-18T09:06:38.538375
```
to get the all the reports with an expiration datetime in the future or no
expiration datetime, that is all currently active reports, assuming the
current datetime is `2018-10-18T09:06:38.538375`.
### Output format
The default output format is a JSON dump of the reports, in a format specific
to Cygnal.
It is possible to get a more standard GeoJSON output using the `format` query
parameter, typically:
```
> GET /api/v1/reports?format=geojson
```
