Update SearchManager documentation to reflect latest behavior.

 * 

 * <p>Once an application is configured to provide search suggestions, those same suggestions can

 * easily be made available to the system-wide Quick Search Box, providing faster access to its

 * content from on central prominent place. See

 * content from one central prominent place. See

 * Box</a> for more details.

 * suggestions interact with Quick Search Box, and optional ways that you may customize suggestions

 * for your application.

 * 

 * <p><b>Important Note:</b>  By default, your application will not be enabled as a suggestion

 * provider (or "searchable item") in Quick Search Box. Once your app is installed, the user must

 * enable it as a "searchable item" in the Search settings in order to receive your app's

 * suggestions in Quick Search Box. You should consider how to message this to users of your app -

 * perhaps with a note to the user the first time they launch the app about how to enable search

 * suggestions. This gives your app a chance to be queried for suggestions as the user types into

 * Quick Search Box, though exactly how or if your suggestions will be surfaced is decided by Quick

 * Search Box.

 *

 * <p><b>Source Ranking:</b>  Once your application's search results are made available to Quick

 * Search Box, how they surface to the user for a particular query will depend on how many

 * other apps have results for that query, and how often the user has clicked on your results

 * compared to the other apps'.  The apps with the best track record within Quick Search

 * Box will get queried earlier and have a better chance of showing their results in the top few

 * slots.  If there are more results than can be displayed to the user within a screen or two, the

 * results may spill into a "more results" section that groups the remaining results by

 * source.  The newest apps with little usage information are given middle of the road positioning

 * until enough usage information is available to rank it as usual.  The exact formula for ranking

 * the results is not set in stone, but suffice it is to say that providing quality results will

 * increase the likelihood that your app's suggestions are provided in a prominent position, and

 * apps that provide lower quality suggestions will be more likely to be pushed into the spillover

 * area.

 * Search Box, how they surface to the user for a particular query will be determined as appropriate

 * by Quick Search Box ranking. This may depend on how many other apps have results for that query,

 * and how often the user has clicked on your results compared to the other apps - but there is no

 * guarantee about how ranking will occur, or whether your app's suggestions will show at all for

 * a given query.  In general, you can expect that providing quality results will increase the

 * likelihood that your app's suggestions are provided in a prominent position, and apps that

 * provide lower quality suggestions will be more likely to be ranked lower and/or not displayed.

 *

 * <p><b>Search Settings:</b>  Each app that is available to Quick Search Box has an entry in the

 * system settings where the user can enable or disable the inclusion of its results.  Below the

 * name of the application, each application may provide a brief description of what kind of

 * information will be made available via a search settings description string pointed to by the

 * android:searchSettingsDescription attribute in the searchable metadata.

 *

 * <p><b>Shortcuts:</b>  Suggestions that are clicked on by the user are automatically made into

 * shortcuts, or, copied so they can quickly be displayed to the user before querying any of

 * the sources. Thereafter, the shortcutted suggestion will be displayed for the query that yielded

 * the suggestion and for any prefixes of that query.  When multiple shortcuts are made available

 * for a given query, they are ranked based on recency and the number of clicks they have received.

 * You can control how your suggestions are made into shortcuts, and whether they are refreshed,

 * using the {@link #SUGGEST_COLUMN_SHORTCUT_ID} column:

 * android:searchSettingsDescription attribute in the searchable metadata. Note that the

 * user will need to visit this settings menu to enable search suggestions for your app before your

 * app will have a chance to provide search suggestions to Quick Search Box - see the section

 * called "Important Note" above.

 *

 * <p><b>Shortcuts:</b>  Suggestions that are clicked on by the user may be automatically made into

 * shortcuts, which are suggestions that have been copied from your provider in order to be quickly

 * displayed without the need to re-query the original sources. Shortcutted suggestions may be

 * displayed for the query that yielded the suggestion and for any prefixes of that query. You can

 * request how to have your app's suggestions made into shortcuts, and whether they should be

 * refreshed, using the {@link #SUGGEST_COLUMN_SHORTCUT_ID} column:

 * <ul><li>Suggestions that do not include a shortcut id column will be made into shortcuts and

 * never refreshed.  This makes sense for suggestions that refer to data that will never be changed

 * or removed.</li>

 * <li>Finally, to prevent a suggestion from being copied into a shortcut, you may provide a

 * shortcut id with a value of {@link #SUGGEST_NEVER_MAKE_SHORTCUT}.</li></ul>

 * 

 * Note that Quick Search Box will ultimately decide whether to shortcut your app's suggestions,

 * considering these values as a strong request from your application.
