Enables the use of a default search provider.
If you enable this setting, a default search is performed when the user types text in the omnibox that is not a URL.
You can specify the default search provider to be used by setting the rest of the default search policies. If these are left empty, the user can choose the default provider.
If you disable this setting, no search is performed when the user enters non-URL text in the omnibox.
If you enable or disable this setting, users cannot change or override this setting in Google Chrome.
If this policy is left not set, the default search provider is enabled, and the user will be able to set the search provider list.
This policy is not available on Windows instances that are not joined
to a MicrosoftÂ® Active DirectoryÂ® domain.
