Adding own search verticals is a common task in the Search Configuration in SharePoint. Here I want to share a code sample for achieving this programmatically. I hope, this model can be added to SPMeta2. First of all, Search Verticals are dedicated Search Results Pages and links to them. How to add them manually is described on technet:

There is no API in CSOM for that. Luckily, Mikael Svenson found how to get the Search Navigation and contributed to PnP by writing an Extension: web.LoadSearchNavigation. Here is my sample code for adding new Search Verticals programmatically: [source language=“csharp”] NavigationNode searchNav = context.Web.Navigation.GetNodeById(1040); NavigationNodeCollection nodeCollection = searchNav.Children; NavigationNodeCreationInformation everything = new NavigationNodeCreationInformation { Title = “Everyting”, Url = “/search/Pages/results.aspx”, }; NavigationNodeCreationInformation myresults = new NavigationNodeCreationInformation { Title = “My Results”, Url = “/search/Pages/myresults.aspx”, }; nodeCollection.Add(everything); nodeCollection.Add(myresults); context.ExecuteQuery(); [/source]
