Unity WebRequest doesnt download the whole html

Hello, I want to download a html using Unity Webrequest and retrieve the data (its actually google). I want to do this because I want to retrieve the count of results from google search. But when I dwonlload the file, tthe results are just missing. I wrote two different codes but both of them are not working. Heres the first:

 public class SearchGoogle : MonoBehaviour
 {
     public string keyword;
     private string searchwebsite;
     string fileName = "MyFile.html";
 
     string html;
 
     void Start()
     {
         searchwebsite = "https://www.google.com/search?q=" + keyword;
         Debug.Log(searchwebsite);
         StartCoroutine(GetText());
         Debug.Log("Coroutine gets callt");
     }
 
 
 
 
     IEnumerator GetText()
     {
         UnityWebRequest www = UnityWebRequest.Get(searchwebsite);
         yield return www.SendWebRequest();
         
 
         if (www.isNetworkError || www.isHttpError)
         {
             Debug.Log("Error: ");
             Debug.Log(www.error);
         }
         else
         {
             html = www.downloadHandler.text;
             checkfor();
             
 
             //filecreation
             var sr = File.CreateText(fileName);
             sr.WriteLine(www.downloadHandler.text);
             sr.Close();
         }
     }
     void checkfor()
     {
         string input = html;
         string search = "<div id=\"result-stats\">";
         int p = input.IndexOf(search);
         if (p >= 0)
         {
             // move forward to the value
             int start = p + search.Length;
             // now find the end by searching for the next closing tag starting at the start position, 
             // limiting the forward search to the max value length
             int end = input.IndexOf("</div>", start);
             if (end >= 0)
             {
                 // pull out the substring
                 string v = input.Substring(start, end - start);
                 Debug.Log(v);
                 // finally parse into a float
                 float value = float.Parse(v);
                 Debug.Log("Value = " + value);
             }
             else
             {
                 Debug.Log("Bad html - closing tag not found");
             }
         }
         else
         {
             Debug.Log("result-stats div not found");
         }
     }
 }

The second is this:

 public class test : MonoBehaviour
 {
     public string keyword;
     private string link;
 
     void Start()
     {
         link = "http://google.com/search?q=" + keyword;
         StartCoroutine(DownloadFile());
     }
 
     IEnumerator DownloadFile()
     {
         var uwr = new UnityWebRequest(link, UnityWebRequest.kHttpVerbGET);
         string path = Path.Combine(Application.persistentDataPath, "unity3d.html");
         uwr.downloadHandler = new DownloadHandlerFile(path);
         yield return uwr.SendWebRequest();
         if (uwr.isNetworkError || uwr.isHttpError)
             Debug.LogError(uwr.error);
         else
             Debug.Log("File successfully downloaded and saved to " + path);
     }
 }

I would really apreciate if someone could tell me why, none could tell me over at stack.
