I am working on search functionality for a mobile website. We are using a drop down list of smart auto complete suggestions so that the user won't have to type as much. In this case, a travel app, the suggestions link directly to a destination, hotel, restaurant or attraction instead of a search results page. Which we have found to be a better experience for the user. However in the space between search box and keyboard we can only fit a relatively small number of results.
We are obviously doing our best to prioritize them but we are wondering if anyone would actually scroll the list (behind the keyboard) or if they just keep typing if they don't immediately see the result they are looking for. Is it worth adding results behind the keyboard?
