How to force some commands to run by using certain index

Hi,
Can i force some of the update command by using the
index that i want. Normally when we update something, we
will let sql to select the index, how can i choose the
index that i want in the transact-sql statement?
Can anyone teach me and give me an example?
Thanks a lot!

Yes, you can use optimizer hints. But a common advice is to do everything
else before using hnts. Check how to tune queries, including optimzer hints,
