Work-search log: how detailed does it need to be? after 6 years as a forklift operator

The certification asks how many work-search activities I did and I do not know what qualifies. There are 6 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 was asked for my log once, after six months. Having it in a spreadsheet made it painless.
