Heading Hierarchy on search results page

What should the heading hierarchy be for a search results page? I am having a hard time trying to figure this out. We are developing a new search results page and looking at Google search results, the individual results are H3, but it looks like there is no H2 heading, or at least it's not showing as H2 using WAVE.

My assumption is that H2 is used to group results but our page won't be including groups of results, it's just one page with individual results and the search bar.
