*** ** * ** ***

This superclass can be used to create a simple search suggestions provider for your application.
It creates suggestions (as the user types) based on recent queries and/or recent views.

In order to use this class, you must do the following.

- Implement and test query search, as described in `https://developer.android.com/reference/android/app/SearchManager`. (This provider will send any suggested queries via the standard `https://developer.android.com/reference/android/content/Intent#ACTION_SEARCH` Intent, which you'll already support once you have implemented and tested basic searchability.)
- Create a Content Provider within your application by extending `https://developer.android.com/reference/android/content/SearchRecentSuggestionsProvider`. The class you create will be very simple - typically, it will have only a constructor. But the constructor has a very important responsibility: When it calls `https://developer.android.com/reference/android/content/SearchRecentSuggestionsProvider#setupSuggestions(java.lang.String,%20int)`, it *configures* the provider to match the requirements of your searchable activity.
- Create a manifest entry describing your provider. Typically this would be as simple as adding the following lines:

  ```
       <!-- Content provider for search suggestions -->
       <provider android:name="YourSuggestionProviderClass"
                 android:authorities="your.suggestion.authority" />
  ```
- Please note that you *do not* instantiate this content provider directly from within your code. This is done automatically by the system Content Resolver, when the search dialog looks for suggestions.
- In order for the Content Resolver to do this, you must update your searchable activity's XML configuration file with information about your content provider. The following additions are usually sufficient:

  ```
       android:searchSuggestAuthority="your.suggestion.authority"
       android:searchSuggestSelection=" ? "
  ```
- In your searchable activities, capture any user-generated queries and record them for future searches by calling `https://developer.android.com/reference/android/provider/SearchRecentSuggestions#saveRecentQuery(java.lang.String,%20java.lang.String)`.
