CMS - 11.4.0

Commerce - 11.8.2

Find - 12.7.1

I have created a custom plugin to appear in the left pane:

    [ServiceConfiguration(typeof(IContentRepositoryDescriptor))]
    public class InstallerRepositoryDescriptor : ContentRepositoryDescriptorBase
    {
//
}

    public class InstallerRoot : ContentAssetFolder
    {
        public override void SetDefaultValues(ContentType contentType)
        {
            base.SetDefaultValues(contentType);
        }

        [UIDescriptorRegistration]
        public class InstallerRootDescriptor : UIDescriptor
        {
            public InstallerRootDescriptor() : base("epi-iconPeopleContextual") { }
        }
    }

Etc... this is all working as expected

The issue I am having is using the CMS search box to easily find the content. The site is using Find out of the box and it works for pages without issues, just not this custom repository.

I have used fiddler and when using the search box for Pages the call is:

 /EPiServer/shell/Stores/searchresults/?parameters=%7B%22filterOnDeleted%22%3Atrue%7D&filterOnCulture=false&searchRoots=1&providerId=EPiServer_Find_Cms_SearchProviders_EnterprisePageSearchProvider&searchQuery=terms&dojo.preventCache=1534426139153

But when using the search box on the custom tab the call is:

 /EPiServer/shell/Stores/searchresults/?parameters=%7B%22filterOnDeleted%22%3Atrue%7D&filterOnCulture=false&searchRoots=30&providerId=EPiServer_Find_Commerce_EnterpriseCatalogSearchProvider&searchQuery=andy&dojo.preventCache=1534426153984

The only difference I can see is the providerId, one using Find_Cms_Search and the one not working using Find_Commerce.

Is this a know bug/issue/limitation or do I need to do something to get the CMS Search working on this custom content repository.

I can confirm that this content is indexed correctly in Find
