HowTo create a hash index in ArangoDB via its HTTP API - rest

Question

I'm trying to create a hash index in ArangoDB via its HTTP API via CURL.
Within my ArangoDB I have several databases like:
production
staging
test
As mentioned in the docs in https://docs.arangodb.com/3.4/HTTP/Indexes/Hash.html one should call the "Index API" with an URL scheme as follows:
http://localhost:8529/_api/index?collection=products
Applied to my use case I have the following URL:
http://localhost:8529/_api/index?colletion=NodesElectric
Executing the CURL command always returns with an error like:
{
"error": true,
"errorMessage": "collection or view not found",
"code": 404,
"errorNum": 1203
}
I suppose that the problem is caused by having the collection "NodesElectric" in all databases "production", "staging",...
My question is how do I specify the according database for the mentioned collection?
Have not found an hint in the docs herein.
Thanks for any help!

Any operation triggered via ArangoDB's HTTP REST API is executed in the context
of exactly one database. To explicitly specify the database in a
request, the request URI must contain the database name in front of
the actual path:
http://localhost:8529/_db/mydb/... where ... is the actual path to the
accessed resource. In the example, the resource will be accessed in
the context of the database mydb. Actual URLs in the context of mydb
could look like this:
http://localhost:8529/_db/mydb/_api/version
This information can be found in the documentation:
https://docs.arangodb.com/3.4/HTTP/Database/
If no database is specified in the request URL, the _system database is used by default.
To create a hash index on collection NodesElectric in your database production the following URL has to be used:
http://localhost:8529/_db/production/_api/index?collection=NodesElectric
