Keep different search histories for different activities?

问题

I have two activities, and I'd like them to each maintain their own search history suggestions. Is that possible? They each have their own search suggestion provider, but I see the same search history appearing for both activities:

// manifest.xml
<activity
  android:name="ActivityA"
  ...
  <meta-data 
    android:name="android.app.searchable"
    android:resource="@xml/searchable_A" />
</activity>

<activity
  android:name="ActivityB"
  ...
  <meta-data 
    android:name="android.app.searchable"
    android:resource="@xml/searchable_B" />
</activity>


// searchable_A.xml
<searchable   
  android:searchSuggestAuthority="providerA" />

// searchable_B.xml
<searchable   
  android:searchSuggestAuthority="providerB" />

When saving the search suggestions, I'm making sure to use the correct provider for each activity.

// ActivityA.java
SearchRecentSuggestions suggestions = new SearchRecentSuggestions(ActivityA.this,
    providerA.AUTHORITY, providerA.MODE);
suggestions.saveRecentQuery(...);

// ActivityB.java
SearchRecentSuggestions suggestions = new SearchRecentSuggestions(ActivityB.this,
    providerB.AUTHORITY, providerB.MODE);
suggestions.saveRecentQuery(...);

Since the search suggestion providers are different, I was expecting them to each maintain a different history. The use case here is that I have an Activity dedicated to cars, and an Activity dedicated to foods. I don't want past search terms to be mixed together, they don't make sense in the different contexts.
