Show more than just a single word on search results page

I think the searchability with documenter could be improved by doing including more info (like a search engine) in the results page. Currently, this is what shows when I search for sin in the Julia Docs:

It's not terrible but I have to click around a lot and not really know if what I am clicking on is what I actually need. I propose something like this:

where the actual info from the page the link goes to is previewed on the search page either to the right or below the title of the item.

I think this will significantly improve the ability for search to be done effectively with documenter.
