........> // or, alternatively
arangosh> view = db["example"]

[ArangoView 82001, "example" (type arangosearch)]

db._view(view-identifier)

Returns the view with the given identifier or null if no such view exists. Accessing views by identifier is discouraged for end users. End users should access views using the view name.

Unknown View:

arangosh> db._view("unknown");

null

Create

db._createView(name, type, properties)

Creates a new View.

name is a string and the name of the View. No View or collection with the same name may already exist in the current database. For more information on valid View names please refer to the naming conventions.

type must be the string "arangosearch", as it is currently the only supported View type.

properties is an optional object containing View configuration specific to each View-type. Currently, only ArangoSearch Views are supported. See ArangoSearch View definition for details.

arangosh> v = db._createView("example", "arangosearch");
arangosh> v.properties()
arangosh> db._dropView("example")
