Backend VLV Index

Backend VLV Indexes are used to store information about a specific search request that makes it possible to efficiently process them using the VLV control.

A VLV index effectively notifies the server that a virtual list view, with specific query and sort parameters, will be performed. This index also allows the server to collect and maintain the information required to make using the virtual list view faster.
