We would like to provide cached results ourselves, but unfortunately it is non-trivial to do so as it requires a lot of storage.

We do have a !cache bang that will take you to a Google cache result. To use it, just search !cache followed by the URL. For example, try the search !cache

To use that easily, you can just copy and paste the URL from a result via your browser's' right-click/long tap menu. We are considering offering an easier way to do this from the interface.
