This is my current layout:
The sentence on top means "Results in the WHOLE SITE for: abc"
"Whole site" becomes the name of the section if you're searching in a single section.
Then you see each result's title in blue and its section in green. The navbar split up the results based on the item type. In this case you have discussion and scenarios which belong to different section types (discussion tool and brainstorming tool) or, for example, if you're searching a single section, you could have item types like "discussion" and "comments", in the case of the discussion tool.
I can say this layout is decent considering I'm not a graphic designer and I have absolutely no background in UI design, web graphic, or anything else related.
Right now I'm looking for general (and maybe some obvious to experts) advice on readability, on the layout of the results page, and anything you can think of.
