  * Create one or more indexes for the collection.

  * Each element in the $indexes array must have a "key" document, which
  * contains fields mapped to an order or type. Other options may follow.
  * For example:
  *
  *     $indexes = [
  *         // Create a unique index on the "username" field
  *         [ 'key' => [ 'username' => 1 ], 'unique' => true ],
  *         // Create a 2dsphere index on the "loc" field with a custom name
  *         [ 'key' => [ 'loc' => '2dsphere' ], 'name' => 'geo' ],
  *     ];
  *
  * If the "name" option is unspecified, a name will be generated from the
  * "key" document.
