Now when you submit a search, the URL contains the search query string. Searching will also go to the `HttpGet Index` action method, even if you have a `HttpPost Index` method.  The following markup shows the change to the `form` tag: ```html

``` ## Adding Search by genre Add the following `MovieGenreViewModel` class to the *Models* folder: [!code-csharp[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Models/MovieGenreViewModel.cs)] The movie-genre view model will contain: * A list of movies. * A `SelectList` containing the list of genres. This will allow the user to select a genre from the list. * `movieGenre`, which contains the selected genre. Replace the `Index` method in `MoviesController.cs` with the following code: [!code-csharp[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Controllers/MoviesController.cs?name=snippet_SearchGenre)] The following code is a `LINQ` query that retrieves all the genres from the database. [!code-csharp[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Controllers/MoviesController.cs?name=snippet_LINQ)] The `SelectList` of genres is created by projecting the distinct genres (we don't want our select list to have duplicate genres). ```csharp movieGenreVM.genres = new SelectList(await genreQuery.Distinct().ToListAsync()) ``` ## Adding search by genre to the Index view Update `Index.cshtml` as follows: [!code-HTML[Main](../../tutorials/first-mvc-app/start-mvc/sample/MvcMovie/Views/Movies/IndexFormGenreNoRating.cshtml?highlight=1,15,16,17,28,31,34,37,43)] Examine the lambda expression used in the following HTML Helper: `@Html.DisplayNameFor(model => model.movies[0].Title)` In the preceding code, the `DisplayNameFor` HTML Helper inspects the `Title` property referenced in the lambda expression to determine the display name. Since the lambda expression is inspected rather than evaluated, you don't receive an access violation when `model`, `model.movies`, or `model.movies[0]` are `null` or empty. When the lambda expression is evaluated (for example, `@Html.DisplayFor(modelItem => item.Title)`), the model's property values are evaluated. Test the app by searching by genre, by movie title, and by both.
