Results from search bar should have headers

[calvh]

For example, when I search for "serializers", I get several results each with the same Heading, "Serializers". The first result is a link to a list of third-party packages. I think the result headings should be something like:

• Third-party packages: Serializers
• API: Serializers
• Tutorial: Serializers

A separate feature might be to have the API results always appear on top, perhaps followed by tutorial results.
