Work-search log: how detailed does it need to be?

The certification asks how many work-search activities I did and I do not know what qualifies. Any experience at all would help. My state says to keep records for a year. Has anyone been audited?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

I record the date, the company, the job title, how I applied and any contact name. It takes a minute each and it covered me when I was asked for proof.
