However, when I watched how an actual person used my online help file, I noticed he didn’t use gerunds in his searches. He typed his search like this: configure monitor display, or reformat hard drive.

When I search on Google, I also do the same: I use the form of the verb that expresses the action I want to do. I’m not looking to “reformatting my hard drive.” I want to “reformat hard drive.” I want to “configure monitor display.” I want to do something, to perform an action.

Grammatically, I think the gerund is more common. But given that the topic title plays a huge role in the search results, I’m thinking of saying goodbye to gerunds in topic titles. When the user searches for “reformat hard drive” the answer will more readily surface if that’s how I’ve named the topic.
