Local database (DB) virtual list view (VLV) indexes allow a client to request a subset of results from a sorted list that match a specific search base, scope, and filter.
The client can navigate through the list by passing a context back to the server with the virtual list view control. The local DB VLV index can be used only when the client request contains the VLV control and the client has been authorized with an access control instruction (ACI) with a targetcontrol of 2.16.840.1.113722.214.171.124.
A client request, which includes a virtual list view control, can be successfully processed without a matching local DB VLV index if the search is completely indexed. This is not an efficient means of using VLV since the server has to retrieve each entry twice.
