```
Optional<ConfigurationPropertySource> get(ConfigurationScope scope)
```
    Provide a configuration property source for the given scope.
    Property sources created by this provider must follow these rules:
    
    A property source only contains properties that are relevant for the given scope. E.g. a global scope property source should not contain any configuration properties for a specific index with the backend.indexes.myindex prefix; if such a property is defined in a global scope source and then overridden in a backend/index scope (without the prefix), the value will be taken from the global source and backend/index ones will be silently ignored.
    
    Property keys must be relative to the scope. No keys should start with hibernate.search. prefix. Assuming we want to redefine a property hibernate.search.backend.directory.type in the backend scope, then Hibernate Search would expect that the property source returned by this provider for a backend scope will contain a value for a directory.type key.
    
    For global-scope property sources, the bean_configurers configuration property is only ever looked up if this provider was registered by a BeanConfigurer added through the Java ServiceLoader system. A provider registered by a BeanConfigurer added through the bean_configurers configuration property cannot itself set the bean_configurers configuration property.
    Parameters:
    
    scope - The scope for which configuration properties are about to be used.
    
    Returns:
    
    An empty optional if the provider does not need to override any Hibernate Search specific defaults for a provided scope, or a ConfigurationPropertySource with overrides otherwise.
  - priority
```
default int priority()
```
    Defines a priority of a particular configuration provider.
    If multiple configuration providers are available they will be sorted by their priority and then by FQCN to guarantee a predictable order.
    
    Returns:
    
    The priority of the current provider.
