Work-search log: how detailed does it need to be? after 5 years as a mechanic

The certification asks how many work-search activities I did and I do not know what qualifies. There are 5 people counting on me, so I am trying to be careful. My state says to keep records for a year. Has anyone been audited?

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.
