onCreate method is called after calling onConfigurationChanged method in an Activity class

I am a beginner in android programming, now i am working on an android application which displays the data in a sort order by default and also provides a search facility. For this i have written an activity called search that will search the contents and displays in a listview. My problem is when i rotate the device the onCreate method of the Activity class is called even after overridding the onConfigurationChanged method. I had also done the following changes in the manifest file to invoke the onConfigurationChanged method.

<activity
             android:name=".Search"
             android:configChanges="orientation|keyboardHidden"
             android:screenOrientation="sensor" >
         </activity>
 

my activity class snippet as follows.

public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
   System.out.println("HERE AT ONCREATE");
      }
 
         @Override
     public void onConfigurationChanged(Configuration newConfig) {
         super.onConfigurationChanged(newConfig);
         System.out.println("HERE AT ON CONFIGURATION CHANGED");
         if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
             setContentView(R.layout.search_port);
         } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
             setContentView(R.layout.search_land);
         }
     }
 

So the output while rotating the device will be
HERE AT ON CONFIGURATION CHANGED
HERE AT ONCREATE

I dont want to get the ONCREATE method called while rotating the device. Please help me to solve this issue. I am using Android 2.2 SDK with samsung Galaxy Tab (7 inch display).
