  string MyString = "";
            if (TxtBN.Text != "")
            {
                MyString = TxtBN.Text;
            }
            else if (TxtAuthor.Text != "")

            {
                string Address = "http://www.stmarksbookshop.com/search/apachesolr_search/" + MyString;
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Address);
                WebResponse response = null;
                StreamReader reader = null;
                response = request.GetResponse();
                reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                string result = reader.ReadToEnd();
                reader.Close();
                if (result.Contains("Search results"))
                {
                    int k = result.IndexOf("";
                    StreamWriter sr1 = new StreamWriter(Path + "Default.aspx");
                    sr1.WriteLine(Code);
                    sr1.Close();
                    Response.Redirect("Default.aspx");
                }
                else
                {
                    LblMsg.Text = "No Data Found";
                }

 ITs NOT clear to me.
do  i put that code on  search button click.
my problem is that
I have created a  auction website and I need to have a search engine on master page. When I type 'belt', all the words containing belt should appear.   I used a textbox, a button,   I type the text I wanna search into the textbox, and click the button. Information will appear on the  page
 like

 i have various item on  page. that detail infomation is store  in db.(like belt price ,pic, size.colour etc.)
 when user type  belt.
is move to belt page ---> like that  ->home-> men-> accc-> belt
direct. then it  show its detail from db

Hi friend,

first get the page source like

            WebRequest Request = WebRequest.Create("URL"); 

            WebResponse Response = Request.GetResponse(); 

            Stream RStream = Response.GetResponseStream();
               
            Encoding en = System.Text.Encoding.GetEncoding("utf-8");

            StreamReader read = new StreamReader( RStream, en );

            string str=read.ReadToEnd();

and made searches in the str(source page) and display on default page
