【译】MVC3 20个秘方-（10）根据关键字搜索
问题
当排序和分页和过滤都不够帮用户去找到他们想要的结果时，想一个最好的备选方式是让用户输入（关键字）他们想要什么。
解决方案
用HtmlHelper创建一个新的From和 文本输入框，并且借助LINQ根据用户输入的关键字在之前过滤过的结果里查找。
讨论
和前边的秘方很像，添加一个根据keyword 搜索的功能需要更新Book/Index view 和BookController。在View里添加一个新的from和textbox 让用户输入keyword。同时也要确保当用户改变排序规则、过滤、分页时，关键字保持。
下边的代码是对View的更新：
@model PagedList.IPagedList<MvcApplication.Models.Book>
<h2>@MvcApplication4.Resources.Resource1.BookIndexTitle</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<p>
Show:
@if (ViewBag.CurrentFilter != "")
{
@Html.ActionLink("All", "Index", new
{
sortOrder = ViewBag.CurrentSortOrder,
Keyword = ViewBag.CurrentKeyword
})
}
else
{
@:All
}
|
@if (ViewBag.CurrentFilter != "NewReleases")
{
@Html.ActionLink("New Releases", "Index", new
{
filter = "NewReleases",
sortOrder = ViewBag.CurrentSortOrder,
Keyword = ViewBag.CurrentKeyword
})
}
else
{
@:New Releases
}
|
@if (ViewBag.CurrentFilter != "ComingSoon")
{
@Html.ActionLink("Coming Soon", "Index", new
{
filter = "ComingSoon",
sortOrder = ViewBag.CurrentSortOrder,
Keyword = ViewBag.CurrentKeyword
})
}
else
{
@:Coming Soon
}
</p>
@using (Html.BeginForm())
{
@:Search: @Html.TextBox("Keyword")<input type="submit" value="Search" />
}
@Html.Partial("_Paging")
<table>
<tr>
<th>
@Html.ActionLink("Title", "Index", new
{
sortOrder = ViewBag.TitleSortParam,
filter = ViewBag.CurrentFilter,
Keyword = ViewBag.CurrentKeyword
})
</th>
<th>
@Html.ActionLink("Isbn", "Index", new
{
sortOrder = ViewBag.IsbnSortParam,
filter = ViewBag.CurrentFilter,
Keyword = ViewBag.CurrentKeyword
})
</th>
<th>
Summary

<th>
@Html.ActionLink("Author", "Index", new
{
sortOrder = ViewBag.AuthorSortParam,
filter = ViewBag.CurrentFilter,
Keyword = ViewBag.CurrentKeyword
})

<th>
@Html.ActionLink("Price", "Index", new
{
sortOrder = ViewBag.PriceSortParam,
filter = ViewBag.CurrentFilter,
Keyword = ViewBag.CurrentKeyword
})

<th>
@Html.ActionLink("Published", "Index", new
{
sortOrder = ViewBag.PublishedSortParam,
filter = ViewBag.CurrentFilter,
Keyword = ViewBag.CurrentKeyword
})

@foreach (var item in Model)
{
<tr>

@Html.DisplayFor(modelItem => item.Title)
</td>
<td>
@Html.DisplayFor(modelItem => item.I
