 /**

  * View type for Maintenance documents

  *

  * <p>

  * Supports doing a search against a data object class or performing a more advanced query. The view

  * type is primarily made up of two groups, the search (or criteria) group and the results group. Many

  * options are supported on the view to enable/disable certain features, like what actions are available

  * on the search results.

  * </p>

  *

  * <p>

  * Works in conjunction with <code>LookupableImpl</code> which customizes the view and carries out the

  * business functionality
