Remove an item from the index of FAST Search

One question that often comes up when working with FAST Search for SharePoint How can I remove an item from the index immediately? Why would you want to do this? The item could be confidential and you cannot wait until the next crawl. Microsoft SharePoint 2010 Search provides an easy way to do this.

2 - Next, go to the Crawl Logs in the FAST Content SSA and search for the crawl log of the URL identified in the previous step. The information you are looking for is its Item ID.
