Can anyone tell me how I should change the following to search for Members who have the extended property organisationName = "test org"? The code runs but returns no results, I don't think I have it structured properly.

    if (ExamineManager.Instance.TryGetIndex("MembersIndex", out var index))
    {
           var searcher = index.GetSearcher();
           var results = searcher.CreateQuery("members").NodeTypeAlias("member").And().Field("organisationName", "test org").Execute();
           if(results.Any())
           {
                ....
           }
     }
