Hi friend,

    use the below coding to search web page.

if (TextBox1.Text != "")
            {
                int count = 0,count1=0,count2=0,count3=0;
                string final="", final1="", final2="", final3="";
                string address3 = "http://www.scholarpedia.org/article/Special:Search?from=sidebar&search="+TextBox1.Text+"&go=Title";
                HttpWebRequest request3=(HttpWebRequest)WebRequest.Create(address3);
                WebResponse response3=request3.GetResponse();
                StreamReader reader3=new StreamReader(response3.GetResponseStream(),Encoding.UTF8);
                string result3 = reader3.ReadToEnd();
                reader3.Close();
                if (result3.Contains("Scholarpedia"))
                {
                    int i = result3.IndexOf("Search results");
                    int j = result3.IndexOf("");
                    final = result3.Substring(i, j - (i));

                    int k = result3.IndexOf("Search results");

Below code will help you in searching your website. It will scan through all the files in your application folder. Hope this helps you.
Code
Const fsoForReading = 1

Dim strSearchText
strSearchText = Request("SearchText")

'Now, we want to search all of the files
Dim objFSO
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")

Dim objFolder
Set objFolder = objFSO.GetFolder(Server.MapPath("/"))

Dim objFile, objTextStream, strFileContents, bolFileFound
bolFileFound = False

For Each objFile in objFolder.Files
If Response.IsClientConnected then
    Set objTextStream = objFSO.OpenTextFile(objFile.Path,fsoForReading)

    strFileContents = objTextStream.ReadAll

    If InStr(1,strFileContents,strSearchText,1) then
       Response.Write "
                      """>" & objFile.Name & "
"

       bolFileFound = True
    End If

    objTextStream.Close
End If
Next

if Not bolFileFound then Response.Write "No matches found..."

Set objTextStream = Nothing
Set objFolder = Nothing
Set objFSO = Nothing
