Bug summary

Create a controller either SurfaceController or RenderMVCControler and add the following code.

if (ExamineManager.Instance.TryGetIndex("ExternalIndex", out var index))
            {

                string[] words = q.Split(' ');


                List<string> newQuery = new List<string>();

                foreach (var word in words)
                {
                    newQuery.Add(word);
                }

                var searcher = index.GetSearcher();
                var results = searcher.CreateQuery("content").GroupedOr(new[] {"pageTitle","pageDescription","pageLayout"}, newQuery.ToArray()).And().Field("umbracoNaviHide", true).Execute(20).OrderByDescending(o=>o.Score).ToList();
                
                //Code removed as not relevant
            }

Change the field params to your own but create a bool either umbracoNaviHide or any other, now run the code and you will get the error.

Change the value of umbracoNaviHide to a string and try again, no error but pages are still returned even when the value is “1”, or “0”.

Expected result

I would expect that if the value is true or false, or “1” or “0”, for that page to not show/show in the results.

Actual result

If you enter a bool true or false you get the error as described if you enter “1” or “0”, all pages are still returned
