As far as I can understand, you want to have details information displayed in each carousel item for a particular item from the source collection. Am I right or am I missing something ? If so, you can customize the template of CarouselItem as illustrated in this article.
Considering the searching functionality, you should implement it on your own so that it run through all the items, find the one you want and call BringDataItemIntoView method of carousel for example.
All the best,
