/**
 * SearchController executes a search and returns matching objects in a paged list.

 * The controller supports the following actions:
 *
 * <div class="controller-action">
 * <div> __Action__ _default_ </div>
 * <div>
 * Search.
 * | Parameter              | Description
 * |------------------------|-------------------------
 * | _in_ / _out_ `query`   | The query string
 * | __Response Actions__   | |
 * | `ok`                   | In all cases
 * </div>
 * </div>
