For example, imagine a library of a hundred medical presentations given at a conference. A doctor is only interested in a specific topic and does not have the time to watch each hour-long show to retrieve the content that she is specifically interested in. She issues a search for “lumbar lordosis” and is returned a set of presentations, ranked by their textual relevance to the query.

She notices that the top-ranked cast contains eight internal matches and opens that up.

There she finds the slides ranked by their relevance. She selects the first match entitled “lateral view lumbar lordosis” and plays it. The presentation launches at time 07:15 and takes her directly to content. She still has access to the remainder of the presentation and can view every other slide if she so wishes.

She could also search for content from within the presentation. Every skin has a search bar. The same search entered on the skin would return a ranked list of the most relevant slides within that presentation.
