Removing extras from passed-in Intent

I have a search screen which can be launched from clicking on a "name" field of another screen.

If the user follows this workflow, I add an extra to the Intent's Extras called "search". This extra uses the text populating the "name" field as its value. When the search screen is created, that extra is used as a search parameter and a search is automatically launched for the user.

However, since Android destroys and recreates Activitys when the screen rotates, rotating the phone causes an auto-search again. Because of this, I'd like to remove the "search" extra from the Activity's Intent when the initial search is executed.

I've tried doing this like so:

    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        if (extras.containsKey("search")) {
            mFilter.setText(extras.getString("search"));
            launchSearchThread(true);
            extras.remove("search");
        }
    }

However, this isn't working. If I rotate the screen again, the "search" extra still exists in the Activity's Intent's Extras.

Any ideas?
