title: Android: saerchable.xml and searchSuggestThreshold parameter
body: <p>I have a search function in my project. In the searchable.xml, i would like to limit the search only when user types at least 3 characters.</p>
  
  <p>This can be done with  android:searchSuggestThreshold="3" but in my case, nothing happens, the user can still perform a search when he types on or more characters.</p>
  
  <p>Here is my searchable.xml:</p>
  
  <pre><code>&lt;searchable xmlns:android="http://schemas.android.com/apk/res/android"
      android:label="@string/Label"
      android:hint="@string/Hint"
      android:searchSuggestThreshold="3"
      android:includeInGlobalSearch="true"/&gt;
  </code></pre>
  
  <p>Here is the 2 search activityes from the Manifest</p>
  
  <pre><code> &lt;activity android:name=".Search"
          android:configChanges="orientation|keyboardHidden"&gt;
            &lt;intent-filter&gt;   
          &lt;action android:name="android.intent.action.SEARCH" /&gt;
          &lt;/intent-filter&gt;
          &lt;meta-data android:name="android.app.searchable"
                 android:resource="@xml/searchable"/&gt;   
          &lt;/activity&gt;
  
           &lt;activity android:name=".SearchInterface"
          android:configChanges="orientation|keyboardHidden"&gt;
           &lt;meta-data android:name="android.app.default_searchable"
                 android:value=".Search" /&gt;
           &lt;/activity&gt;
  </code></pre>
