Search presence: evaluate content types

Let's review all content types that could appear in a search result, and determine what information should be present to maximize context for the resident so that they can accomplish their goals. This will serve as a model going forward as we create new content types and evaluate them during development for search presence.

Here's the sheet we're working from: https://docs.google.com/spreadsheets/d/1KIA-En47Ah4aE1VcwQtcPzsgLYv32cHNis6rLUVmJ38/edit#gid=0
