- * <p>In terms of implementation, there are three broad classes of Applications:
- * <ol>
- * <li>Applications that are not inherently searchable</li>
- * <li>Query-Search Applications</li>
- * <li>Filter-Search Applications</li>
- * </ol>
- * <p>These categories, as well as related topics, are discussed in
- * the sections below.
+ * <p>To make search appear to the user as a seamless system-wide feature, the application
+ * framework centrally controls it, offering APIs to individual applications to control how they
+ * are searched. Applications can customize how search is invoked, how the search dialog looks,
+ * and what type of search results are available, including suggestions that are available as the
+ * user types.
  *
- * <p>Even if your application is not <i>searchable</i>, it can still support the invocation of
- * search.  Please review the section <a href="#HowSearchIsInvoked">How Search Is Invoked</a>
- * for more information on how to support this.
- * 
- * <p>Many applications are <i>searchable</i>.  These are 
- * the applications which can convert a query string into a list of results.  
- * Within this subset, applications can be grouped loosely into two families:  
- * <ul><li><i>Query Search</i> applications perform batch-mode searches - each query string is 
- * converted to a list of results.</li>
- * <li><i>Filter Search</i> applications provide live filter-as-you-type searches.</li></ul>
- * <p>Generally speaking, you would use query search for network-based data, and filter 
- * search for local data, but this is not a hard requirement and applications 
- * are free to use the model that fits them best (or invent a new model).
- * <p>It should be clear that the search implementation decouples "search 
- * invocation" from "searchable".  This satisfies the goal of making search appear
- * to be "universal".  The user should be able to launch any search from 
- * almost any context.
+ * <p>Even applications which are not searchable will by default support the invocation of
+ * search to trigger Quick Search Box, the system's 'global search'.
