The intent filter is specified within the Activity tag and you can specify multiple filters per activity.

<activity android:name=".activities.WaypointMap" android:launchMode="singleTop" android:theme="@style/Theme.NoBackground">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
    <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" />
</activity>
<activity android:name=".activities.WaypointList" android:launchMode="singleTop">
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
    <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" />
</activity>
