Creating a Search bar c# MVC
<p>I am trying to create a search bar within my MVC application. I have the following model</p>

<pre><code>    public class Project
{
    public int projectID { get; set; }
    public int customerID { get; set; }
    public int departmentID { get; set; }
    public string projectName { get; set; }
    public int employeeID { get; set; }
}
</code></pre>

<p>I want to create a search bar within my index view allowing users to search the list of projects by entering either the projectID or the projectName. So far I have it searching on projectName but I am unsure how (or if it's possible) to search by ID or both at the same time. 
This is the search bar in my Index view :</p>

<pre><code>   @using (Html.BeginForm())
{
&lt;p&gt;
    Name  : @Html.TextBox("SearchName")&lt;br /&gt;
    &lt;input type="submit" value="Search" /&gt;
&lt;/p&gt;
}
</code></pre>

<p>This is my controller method </p>

<pre><code>    public ActionResult Index(string searchName)
    {

        var projects = from pr in db.projects select pr;

        if (!String.IsNullOrEmpty(searchName))
        { 
            projects = projects.Where(c =&gt;  c.projectName.Contains(searchName));
      }

        return View(projects);
      }
</code></pre>

<p>Any advice or help would be greatly appreciated! Thanks</p>
