From the Ad Hoc Index Browser, the Cancel Build Index command from the Ad Hoc Index menu enables you to cancel a build that is in progress.
To cancel the building of an ad hoc index definition
In the Ad Hoc Index Browser, select the index definition that is in the process of being built (that it, it has a bright yellow background in the Status column).
Select the Cancel Build Index command from the Ad Hoc Index menu.
The background color of the Status column then changes to light pink and Unpopulated is displayed when the partially built index has been removed from the dynamic dictionary instance.
