How do you redirect to a new page from Ajax.Beginform in MVC5?

Question

I"m not sure if using Ajax.Beginform is even the right method for this, I have tried a few different things at this point.

I have a textbox and a button that users can use to search a database with. They are located on my _layout page. I originally had this on my index page and was using ajax.begin form to render a partial view. I want to display URL's to the user so they can navigate properly in the browser, so I have moved the search section to my _layouts page and I want to hook it up so that if they are on the index page, it does a postback to a search page. If they are on the search page then it would render the partial view.

I am stuck trying to get it to just navigate to a new page. I've tried using the Ajax.begin form (Code below) and adding code to the button directly (also below) but have not gotten it to redirect. With the Ajax I see a response come back in the Network tab of the browser debug window, but it doesn't render on the page.

Here's the code:

Ajax Attempt:

@using (Ajax.BeginForm("Search", "Home", new AjaxOptions { HttpMethod = "GET" })) {

            <div class="form-group" style="width:85%;">
                <div class="right-inner-addon">
                    <i class=" glyphicon glyphicon-search"></i>
                    <input type="text" data-autocomplete="@Url.Action("Quicksearch","Home")" class="form-control" placeholder="Search" name="q" value="@ViewBag.CurrenetFilter" />
                </div>
            </div>
            <div class="form-group">
                <button class="btn btn-default form-inline" type="submit">Search</button>
            </div>
        }
        <br />

    </div>

</div>
@RenderBody()

This is on the home controller:

   public ActionResult Search(string q, int? page,  string catb = null)
    {
       return RedirectToAction("Search", "Items", new { query = q, pageNum = page, categoryB = catb });
    }

This is on the Items controller:

 public ActionResult Search(string query, int? pageNum, string categoryB = null)
    {


        var pageNumber = pageNum ?? 1; // if no page was specified in the querystring, default to the first page (1)

        var items = db.items_with_descriptions
           .Where(r => r.category_c.Contains(query) && r.category_b.Contains(categoryB) || string.IsNullOrEmpty(query) || string.IsNullOrEmpty(categoryB))
            .OrderBy(r => r.level);

        var onePageOfProducts = items.ToPagedList(pageNumber, 10); // will only contain 25 products max because of the pageSize

        if (!string.IsNullOrEmpty(query))
        {
            ViewBag.CurrenetFilter = query;
        }

        //delete

        if (!string.IsNullOrEmpty(categoryB))
        {
            ViewBag.Catb = categoryB;
        }

        ViewBag.OnePageOfProducts = onePageOfProducts;
        return View(items.ToPagedList(pageNumber, 10));
    }

Lastly, I've also tried removing the ajax reference and adding the following to the button:

<button class="btn btn-default form-inline" type="submit" onclick="window.location.href=@Url.Action("Search", "items",new {q=@ViewBag.CurrenetFilter})">Search</button>

Nothing happens when I do this.
