Vulnerability in EPiServer.Forms
Is it possible to exclude a specific catalog or commerce category from being indexed in Find?
To exclude a specific catalog from indexing, it can be quite easy, but for category it can be much tricker.
ContentIndexer.Instance.Conventions.ForInstancesOf<EntryContentBase>().ShouldIndex(x => x.CatalogId != 5);
For category you'll likely need to use IRelationRepository to check if a entry belongs to that specific node or not.
