My server is named "my_server." When I look at the keys in search_api.server.my_server.yml, I see...
backend_config:
retrieve_data: false
highlight_data: false
site_hash: false
server_prefix: ''
domain: generic
environment: default
connector: standard
connector_config:
scheme: http
host: example.my.test
So it looks like I should be able to override the host in settings.php with...
$config['search_api.server.my_server']['backend_config']['connector_config']['host'] = 'mytest';
However, this has no effect on the host value displayed at /admin/config/search/search-api/server/my_server/edit
What am I missing?
