/filter/bybox

URL: http://<db.host>:<db.port>/filter/bybox

Calculates how many objects within the given table lie in a rectangular box. The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set which satisfies the input NAI restriction specification is also created when a input parameter view_name is passed in as part of the input payload.

true
false

collection_name

[DEPRECATED--please specify the containing schema for the view as part of input parameter view_name and use /create/schema to create the schema if non-existent] Name of a schema for the newly created view. If the schema is non-existent, it will be automatically created.
