 * Search results are collected by implementing this interface

 * visual, it is recommended that the match is shown as soon
 * as it is collected (rather than kept in a list and presented
 * at the end of the search). This interface should be implemented 
 * when you want to support collection of results from a mirror site,
 * otherwise you can just implement the IUpdateSearchResultsCollector.
  * <p>
 * <b>Note:</b> This class/interface is part of an interim API that is still under development and expected to
 * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
 * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
 * (repeatedly) as the API evolves.
 * </p>
 * @since 3.1
 * @deprecated The org.eclipse.update component has been replaced by Equinox p2. This
 * provisional API was never promoted to stable API, and may be removed from a future release of the platform.
