How to Enter a Polygon into Facet Search

The leaflet map allows you to either draw a polygon or a bounding box to constrain your results geographically.

There is also a polygon textbox that will give you the exact coordinates, which you can paste into geojson.io or an AOI.

Recently, we realized that you can actually enter your own coordinates into the textbox, following the geojson format of  bracketed coordinates, like the example below.

Once you move your focus off the polygon textbox, Leaflet will automatically update its geographic constraint.
