Cron not function properly

I have setup a cron in order to run a search at 8am everyday. Here is the syntax:

* 08 * * *

The search did get executed at 8am, but ran every minute between 8-9am.
I only need the search to run once each day.

Thoughts?

Well the initial * in your cron schedule specifies the minute, so when you specify * 8 at the beginning that's equal to saying every minute when the hour has the value 8. In order to have it run just at 8:00, just put 0 in the minute part:

0 8 * * *

the first * specifies the every minute. so you should write like 0 8 * * *
