No-op Search Control
Instead of actually performing a search request, a searchResultDone message is returned, with a response control whose value contains:
This control is experimental; no formal specification exists yet. As such, it may change in the future.
- the result code the search would return; it may differ from the result code returned by the search when the control does not modify its semantics
- the number of entries the search would return
- tne number of search references the search would return.
