Custom code which views use to customize how dnn search treats data of that view.
It's meant for customizing the internal indexer of the platform, _not_ for Google Search.

To use it, create a custom code (.cs) file which implements ICustomizeSearch interface.
You can also inherit from a DynamicCode base class (like Code12) if you need more functionality.

For more guidance on search customizations, see https://r.2sxc.org/customize-search
