Distance

This is the unique search type in the filter. Distance is used only in the GPS Coords item. It works with coordinates. Distance accepts two values:

Place
Radius of searching

In filters list we can see:

{
  "data_type": "gps_coords",
  "field_id": 625329,
  "search_type": "distance",
  "selected_search_option_variable": "Value",
  "valuesArray": [""]
}

Numbers in the following table means search radius in kilometers.

F\S	San Francisco, 4000	New York, 500	London, 0	Tokyo, 24000	Denver, 2000
Boston	-	+	-	+	-
New York	-	+	-	+	-
London	-	-	+	+	-
Tokyo	-	-	-	+	-
San Francisco	+	-	-	+	+

S - search values

San Francisco - type place

4000 - radius in kilometers

F - column of field values
