public class SearchUtil
extends Object

This utility provides methods to easily create and execute queries in the bridge. These methods are replacements for frequently used code snippets which are present in code which uses the query objects in the mmbase bridge. The implementation of these methods can also be used as documentation how to use the search query api.
