You have to think about what shows in the search results.But as i was asking tell me is any search engine shows keywords in search result?
The title of the page appears as the link and then under that is a line or two of text. That text comes from either the content of the page, the meta description and in exceptional cases the domz registry. Under that is the url.
Now that's just 5 things, title, meta description, domz registry, page content and url. That's pretty much the same format for all search engines. Now does that mean that all search engines only use those 5 things to determine a pages position? Of course not. In the case of Google they analyze over 200 different things. They can't possible show 200 things nor would they want to as then people would know exactly what all these things are.
You have to remember that this is all one tiny tiny part of it all so won't have any obvious visual search examples like you tried to show.
