If i'm writtng a book on search user interface design

i'll start with user stories, e.g., a guy who want to study a topic, a guy seeking for a path from zurich to bern, and a guy who want to figure out interesting places around chengdu, as well as a guy who want to plan a interesting weekend with his family, etc.
And continue with the problem behind the scenarios, and current solutions to the problems, and deep into the core of the problems, etc.
Then, i'll figure out the application and research advances in this domain,together with background theory and so on.
And I'll back with previous scenarios by envisioning a better life for the future with the possible advances in near or far future.

Yes, i'm reading the search user interface , it's good but could be great.
