When you create a search configuration, you have the option of associating it with a base search configuration. A base search configuration is like a template that provides settings that can be inherited by standard search configurations. A base search configuration cannot be applied to a search query directly, but standard search configurations that inherit settings from it can be.
You can create any number of base search configurations, and any number of standard search configurations can inherit from a single base search configuration. Note, however, than an individual standard search configuration can inherit from only one base search configuration.
When you define the settings for a standard search configuration that inherits from a base search configuration, you can decide which inherited settings to enable. See Applying Inherited Rules and Applying Inherited Prioritization Settings for more information.
Note that the user interface for specifying the rules and property prioritizations for a base search configuration is virtually identical to the UI for defining standard search configurations. The main difference is that standard search configurations have options for specifying which inherited settings to enable or disable. Base search configuration don’t have these options, because a base search configuration cannot inherit from another base search configuration.
