What is error here on my codes?

Everytime I run it in my phone, the error is "Android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0-s". Can you help me to fix it? :/

here is query..

     public Cursor find(String data)
 {
     SQLiteDatabase db = this.getReadableDatabase();

      Cursor res = db.query(MYDATABASE_TABLE, new String[] { KEY_ID,
              CONTENT_POSITION}, CONTENT_POSITION + "=?",
                new String[] { }, null, null, null, null);

     return res;
 }

and my search codes..

    public void onClick01(View arg0)
    {
        try
        {
        map_search = (EditText) findViewById(R.id.content1);
        String input = map_search.getText().toString();
        // TODO Auto-generated method stub
            Log.d("data input :", input);
            res = mySQLiteAdapter.find(input);
            String result = res.getString(0);
                if(!res.isClosed())
                    {
                    res.close();
                    }

        Log.d("data input :",result);
        double lat=0,lng=0;
        int rslt = Integer.parseInt(result);

        switch(rslt)
        {
        case 3:
            lat = 14.669645;
            lng = 121.003384;
            break;
        }
            LatLng php4 = new LatLng(lat, lng);
               googleMap.setMyLocationEnabled(true);
               googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(php4, 13));
               CameraUpdate center= CameraUpdateFactory.newLatLng(new LatLng(14.669645, 121.003384));
               CameraUpdate zoom=CameraUpdateFactory.zoomTo(18);

                    googleMap.moveCamera(center);
                    googleMap.animateCamera(zoom);
                    googleMap.addMarker(new MarkerOptions()
                      .title("This is your deceased location.")
                      .snippet("try")
                      .position(php4));


                    map_btn.setText("");
