You can have multiple form on a webforms page, but only 1 can have the runat-"server' attribute and the runat="server" form cannot have any nested forms. One option that might work for you:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled</title>
</head>
<body>
    <div id="header>
        <h1>My Site</h1>
        <form id="SearchForm" action="search.aspx" method="post">
            <!--your search form html inputs (on server controls)-->
        </form>
    </div>

    <!-- the standard webforms form used for server controls etc-->
    <form id="form1" runat="server">

            <asp:ContentPlaceHolder ID="SearchBody" runat="server">
            </asp:ContentPlaceHolder>

    </form>
</body>
</html>
